3. Disable ASCII Control characters shortcuts?

Disable ASCII Control characters shortcuts?


  • These are a list of shortcuts for ASCII control characters I’ve found so far. I wish to keep all of them from appearing while I’m typing. I can accidentally hit these shortcuts when I’m trying to use other shortcuts like Ctrl + Z or Ctrl + V, for example. I’m using Windows and I could find no way to remove these from the shortcut mapper.

    ~ Shift + Esc = (ESC)
    ~ Ctrl + E = (ENQ)
    ~ Ctrl + R = (DC2)
    ~ Ctrl + Pause\Break = (ETX)
     ~ Ctrl + Shift + Y = (EM)
    ~ Ctrl + Shift + W = (ETB)
    ~ Ctrl + Shift + O = (SI)
    ~ Ctrl + Shift + A = (SOH)
    ~ Ctrl + Shift + D = (EOT)
    ~ Ctrl + Shift + G = (BEL)
    ~ Ctrl + Shift + H = (BS)
    ~ Ctrl + Shift + Z = (SUB)
    ~ Ctrl + Shift + X = (CAN)
    ~ Ctrl + Shift + C = (ETX)
    ~ Ctrl + Shift + v = (SYN)
    ~ Ctrl + Shift + B = (STX)
    ~ Ctrl + Shift + N = (SO)
    ~ Ctrl + Shift + 6 + (RS)
    ~ Ctrl + Shift + -(Dash) = (US)

  • I find something along these lines an excellent feature suggestion!

  • Couldn’t agree more. Don’t know how many times I’ve done this. Especially Ctrl+Shift+Z.

  • Well, kind of a hack, you could simply assign shortcuts to no action macro, couldn’t you?
    Something like

        <Macro name="RemoveControlCharSUB" Ctrl="yes" Alt="no" Shift="yes" Key="90">
        <Action type="" message="" wParam="" lParam="" sParam="" />
    </Macro>

  • I’m going to shamelessly promote my new plugin. If you install the plugin and put the following code in the startup script it will get rid of most of these shortcuts.

    editor:AssignCmdKey(string.byte('E'), SCMOD_CTRL, SCI_NULL)
editor:AssignCmdKey(string.byte('R'), SCMOD_CTRL, SCI_NULL)
editor:AssignCmdKey(string.byte('E'), SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL)
editor:AssignCmdKey(string.byte('Y'), SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL)
editor:AssignCmdKey(string.byte('W'), SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL)
editor:AssignCmdKey(string.byte('O'), SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL)
editor:AssignCmdKey(string.byte('A'), SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL)
editor:AssignCmdKey(string.byte('D'), SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL)
editor:AssignCmdKey(string.byte('G'), SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL)
editor:AssignCmdKey(string.byte('H'), SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL)
editor:AssignCmdKey(string.byte('Z'), SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL)
editor:AssignCmdKey(string.byte('X'), SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL)
editor:AssignCmdKey(string.byte('C'), SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL)
editor:AssignCmdKey(string.byte('V'), SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL)
editor:AssignCmdKey(string.byte('B'), SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL)
editor:AssignCmdKey(string.byte('N'), SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL)
editor:AssignCmdKey(string.byte('6'), SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL)

  • @dail there is nothing to shame about, you offer a new plugin and a solution to a problem.
    Sounds like a successful day to me ;-)
    And you remembered me about a function AssignCmdKey which I have nearly forgotten.

    So a python script would look like this

    editor.assignCmdKey(ord('E')+(2<<16),2172)
editor.assignCmdKey(ord('R')+(2<<16),2172)
editor.assignCmdKey(ord('Y')+(3<<16),2172)
editor.assignCmdKey(ord('W')+(3<<16),2172)
editor.assignCmdKey(ord('O')+(3<<16),2172)
editor.assignCmdKey(ord('A')+(3<<16),2172)
editor.assignCmdKey(ord('D')+(3<<16),2172)
editor.assignCmdKey(ord('G')+(3<<16),2172)
editor.assignCmdKey(ord('H')+(3<<16),2172)
editor.assignCmdKey(ord('Z')+(3<<16),2172)
editor.assignCmdKey(ord('X')+(3<<16),2172)
editor.assignCmdKey(ord('C')+(3<<16),2172)
editor.assignCmdKey(ord('V')+(3<<16),2172)
editor.assignCmdKey(ord('B')+(3<<16),2172)
editor.assignCmdKey(ord('N')+(3<<16),2172)
editor.assignCmdKey(ord('6')+(3<<16),2172)
editor.assignCmdKey(189+(3<<16),2172)
editor.assignCmdKey(27+(1<<16),2172)

editor.assignCmdKey(19+(2<<16),2172)  # this seems not to work although 19 should be the key code of break key

    Cheers

  • Yeah I’ve always been a fan of the PythonScript plugin (even stole code from that project :)). However for alot of my uses it was over kill in terms of RAM and initialization time to make it worth it.

  • That’s the beauty of having multiple programming/scripting languages, isn’t it. ;-)
    Having lua as npp scripting extension can force me to learn more about it because
    it’s also an extension to wireshark afaik.

    Thank you

  • ok this should do the trick for CTRL+break

    editor.assignCmdKey(3+(KEYMOD.CTRL << 16),2172)

  • After testing again, I saw that SHIFT+ESC still worked, strange.
    So figured out, that

    editor.assignCmdKey(27+(1<<16),2172)

    is wrong and should be

    editor.assignCmdKey(7+(1<<16),2172)

    instead. Hmm…

    So the full list more user friendly

    editor.assignCmdKey(ord('E') + (KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(ord('R') + (KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(ord('Y') + (KEYMOD.SHIFT + KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(ord('W') + (KEYMOD.SHIFT + KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(ord('O') + (KEYMOD.SHIFT + KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(ord('A') + (KEYMOD.SHIFT + KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(ord('D') + (KEYMOD.SHIFT + KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(ord('G') + (KEYMOD.SHIFT + KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(ord('H') + (KEYMOD.SHIFT + KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(ord('Z') + (KEYMOD.SHIFT + KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(ord('X') + (KEYMOD.SHIFT + KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(ord('C') + (KEYMOD.SHIFT + KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(ord('V') + (KEYMOD.SHIFT + KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(ord('B') + (KEYMOD.SHIFT + KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(ord('N') + (KEYMOD.SHIFT + KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(ord('6') + (KEYMOD.SHIFT + KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(189 + (KEYMOD.SHIFT + KEYMOD.CTRL << 16),2172)
editor.assignCmdKey(7 + (KEYMOD.SHIFT << 16),2172)
editor.assignCmdKey(3 + (KEYMOD.CTRL << 16),2172)

  • Thanks! It worked out brilliantly. This was something that always bothered me about Notepad++. I’m not too big a coder myself, and I’m definitely sure I’ll never use those control characters. Glad I finally got rid of these shortcuts.

    I got dail’s plugin working. I couldn’t get Claudia’s python code to work though. I downloaded Python Script 1.0.6 from the plugins manager and upon pressing Show Console, I got an Unknown Exception error message. Pressing the Show Console button again allowed me to popup the console, but I suspect the reason why the console isn’t working because of the unknown exception.

    Running
    editor:AssignCmdKey(string.byte(‘E’), SCMOD_CTRL, SCI_NULL)
    in the console did not change my key assignments.

    In addition to dail’s code, you should also add these 3 lines. I came up with this code thanks to Claudia’s previous code.
    <pre><code>
    editor:AssignCmdKey(3, SCMOD_CTRL, SCI_NULL) – CTRL + PAUSE/BREAK
    editor:AssignCmdKey(7, SCMOD_SHIFT, SCI_NULL) – SHIFT + ESC
    editor:AssignCmdKey(189, SCMOD_CTRL + SCMOD_SHIFT, SCI_NULL) – Ctrl + Shift + -(Dash)
    </pre></code>

    On a side note, I can’t get the markdown for codeblocks to show up in a post’s preview.

  • Running editor:AssignCmdKey(string.byte(‘E’), SCMOD_CTRL, SCI_NULL) in the console did not change my key assignments.

    That’s weird. It works for me. Maybe there is some other plugin or keyboard configuration that is messing with it.

    Thanks for those extra 3 shortcuts. They worked fine for me!

    Also, to fully get rid of those ASCII control codes, you should probably disable those on both “views”. So instead of using editor you should set the shortcut on both editor1 and editor2 instead; for example…

    editor1:AssignCmdKey(3, SCMOD_CTRL, SCI_NULL)
editor2:AssignCmdKey(3, SCMOD_CTRL, SCI_NULL)

    I believe this would also apply to the PythonScript plugin.

  • Hi Danny and All,

    Once you inhibited these shortcuts, you’re still able to write control characters, in your text, with the classical Windows method !

    • Hit down the ALT key

    • While keeping the ALT key pressed, type, on the NUMERIC keypad, the three digits, of a number between 001 and 031

    • Release all the keys => the appropriate Control character should be inserted, at the current cursor position

    For instance : Press ALT and 0 , 1 , 8 would write the 18th letter of the alphabet ( the letter R ) => DC2

    So :

    ALT  +  0 0 1    =>    SOH      ( A )
ALT  +  0 0 2    =>    STX      ( B )
ALT  +  0 0 3    =>    ETX      ( C )
ALT  +  0 0 4    =>    EOT      ( D )
ALT  +  0 0 5    =>    ENQ      ( E )
ALT  +  0 0 6    =>    ACK      ( F )
ALT  +  0 0 7    =>    BEL      ( G )
ALT  +  0 0 8    =>    BS       ( H )
ALT  +  0 0 9    =>    TAB      ( I )
ALT  +  0 1 0    =>    LF       ( J )
ALT  +  0 1 1    =>    VT       ( K )
ALT  +  0 1 2    =>    FF       ( L )
ALT  +  0 1 3    =>    CR       ( M )
ALT  +  0 1 4    =>    SO       ( N )
ALT  +  0 1 5    =>    SI       ( O )
ALT  +  0 1 6    =>    DLE      ( P )
ALT  +  0 1 7    =>    DC1      ( Q )
ALT  +  0 1 8    =>    DC2      ( R )
ALT  +  0 1 9    =>    DC3      ( S )
ALT  +  0 2 0    =>    DC4      ( T )
ALT  +  0 2 1    =>    NAK      ( U )
ALT  +  0 2 2    =>    SYN      ( V )
ALT  +  0 2 3    =>    ETB      ( W )
ALT  +  0 2 4    =>    CAN      ( X )
ALT  +  0 2 5    =>    EM       ( Y )
ALT  +  0 2 6    =>    SUB      ( Z )
ALT  +  0 2 7    =>    ESC      (   )
ALT  +  0 2 8    =>    FS       (   )
ALT  +  0 2 9    =>    GS       (   )
ALT  +  0 3 0    =>    RS       (   )
ALT  +  0 3 1    =>    US       (   )

    Only, the control character NULL can’t be written, with that method. Instead, you’ll use the ASCII Insertion Panel ( Menu Edit - Character Panel ! )

  • Hi @guy038,

    yes, of course, the assignCmdKey is an scintilla internal function only.
    Not sure if I get your point so.

    Cheers

  • @Danny-Phan

    if you are still interested in getting the python script code working I assume
    you need to install the python script plugin by using the msi package.
    It seems that plugin manager has some serious problems with this plugin.

    Cheers
    Claudia
