Macro to switch indentation

[elusiveorganization]

Is it possible to make a shortcut macro to switch between tab and space identation? I’ve tried the following:

<Macro name="Tab (Ctrl + E)" Ctrl="yes" Alt="no" Shift="no" Key="69">
	<Action type="0" message="2124" wParam="0" lParam="1" sParam="" />
</Macro>
<Macro name="Space (Ctrl + R)" Ctrl="yes" Alt="no" Shift="no" Key="82">
	<Action type="0" message="2124" wParam="0" lParam="0" sParam="" />
</Macro>

*2124 is SCI_SETUSETABS(bool useTabs)

It should be… but I couldn’t make it work, either. I believe the bool useTabs argument should be the wParam, not the lParam, but it didn’t work whether I used yours or whether I moved the 1 to wParam instead. I don’t know what’s wrong with that.

<Macro name="Tab (Ctrl + E)" Ctrl="yes" Alt="no" Shift="no" Key="69">
    <Action type="0" message="2124" wParam="1" lParam="0" sParam="" />
</Macro>
<Macro name="Space (Ctrl + R)" Ctrl="yes" Alt="no" Shift="no" Key="82">
    <Action type="0" message="2124" wParam="0" lParam="0" sParam="" />
</Macro>

However, if I use the NppExec plugin, I can send the 2124 Scintilla message and have it toggle the mode, as shown in this animation.

To make those into keyboard-executable scripts in NppExec:

1. Plugins > NppExec > Execute
   1. Make the Command(s): sci_sendmsg 2124 1
   2. Click Save…, name it use-tabs, and click Save
   3. Change the sci_sendmsg 2124 1 to sci_sendmsg 2124 0, and save again as use-spaces
   4. Cancel
2. Plugins > NppExec > Advanced Options, in the Menu Item section:
   1. Name = Use Tabs, Associated Script = use-tabs, Add/Modify
   2. Name = Use Spaces, Associated Script = use-spaces, Add/Modify
   3. Okay twice, then restart Notepad++
3. At this point, Macro > Use Tabs or Macro > Use Spaces will toggle.
4. To set the shortcut, Macro > Modify Shortcut / Delete Macro
   1. Change to Plugin Commands tab.
   2. If available, set Filter to NppExec, otherwise just scroll down until you find the NppExec commands
   3. At the end of the NppExec commands should be Use Tabs and Use Spaces.
   4. Click Modify on each, and set to Ctrl+E and Ctrl+R, or whatever keystrokes you want
   5. Close the shortcuts dialog when don.
   6. Keyboard shortcuts should now work (assuming there wasn’t a conflict with the shortcuts; in v7.6.6 and newer, shortcut conflicts should be highlighted, even with filters active)

Good luck.

Another option would be LuaScript. Edit the startup file, add the following, and restart.

npp.AddShortcut("Toggle Indentation", "Ctrl+E", function()
	editor.UseTabs = not editor.UseTabs
end)
