Is there any plugin that implements some alternative approach to the macros?

There’s SCRIPTING.

Thanks for the hint for using the regular expression with # as marks. I was not thinking about that possibility.

@anyone: The macro recording and playback in Notepad++ is fine for simple things, in my opinion. However, it is difficult to modify the macros (through editing shortcuts.xml). Is there any plugin that implements some alternative approach to the macros?

„this is the text to be quoted“

I see that for the opening quote you used U+201E DOUBLE LOW-9 QUOTATION MARK. I expected you to use U+201F DOUBLE HIGH-REVERSED-9 QUOTATION MARK for the closing quote. Instead you used U+201C LEFT DOUBLE QUOTATION MARK.

The difference is

• „this is the text to be quoted‟ using U+201F
• „this is the text to be quoted“ using U+201C

If you intended to use U+201F then the line in your shortcuts.xml would look like

<Action type="3" message="1602" wParam="0" lParam="0" sParam="„${0}‟" />

The second part that you desire likely could be done in Notepad++. @Mark-Olson already provided you with a hint on how to do it by showing you a search replace that takes the current selection and inserts a „ in front of it and appends a ‟ at the end of it.

If instead you want to type

xxx #this is the text to be quoted#uv xxx

You then run this regular expression search/replace:
** Search: #([^#]+)#uv
Replace: „${1}‟ **

That will replace the #...#uv style marks in your text with „...‟.

If you want to be able to use several styles of quotes using #xx or other things besides #uv then it’s still possible though gets far messier do to it with a single search/replace.

        <Macro name="uv" Ctrl="no" Alt="no" Shift="no" Key="0">
            <Action type="3" message="1700" wParam="0" lParam="0" sParam="" />
            <Action type="3" message="1601" wParam="0" lParam="0" sParam="(?s).*" />
            <Action type="3" message="1625" wParam="0" lParam="2" sParam="" />
            <Action type="3" message="1602" wParam="0" lParam="0" sParam="„${0}“" />
            <Action type="3" message="1702" wParam="0" lParam="896" sParam="" />
            <Action type="3" message="1701" wParam="0" lParam="1609" sParam="" />
        </Macro>

For explaining the second part. The other mentioned editor used the #quoting by hashes#macro_name to ge the same effect. Some shortcut was used to tell that the thing before is the macro name, and the special character is the delimiter (instead of making a selection). It may have been the JED editor that simulates Emacs (using a different inner language). The macros were easily edited, and you could use even more delimiters to wrap the parts, say, by more complex LaTeX macros with more arguments. I am not using it more than 20 years; so, I am not sure whether JED was the one.

I am having a hard time understanding what you are asking for. If you are not a native English speaker, I would recommend writing what you want in your native language, and copy-pasting it into Google Translate rather than trying to do the translation yourself. It sounds like there are two things you want:

1. Wrap the selected text in quotes
2. Add a # and then a name to the end of the selected text

How to wrap the selected text in quotes

Important: while doing steps 2-4, do not click in the text area of the Notepad++ window! If you do, your selection will change and that will become part of the macro.

1. Go to Macro->Start Recording from the Notepad++ main menu bar
2. Go to Search->Replace... from the main menu; the find/replace form will pop up.
3. Set the fields of the find/replace form as follows:
   • Find what: -> (?s).*
   • Replace with: -> „${0}“
   • Wrap around -> checked
   • Search Mode -> Regular expression
   • In selection -> checked
4. Hit the Replace button
5. Go to Macro->Stop Recording from the Notepad++ main menu
6. Try selecting a different area of text and run Macro->Playback from the Notepad++ main menu, and make sure that the macro does what you want
7. Go to Macro->Save Current Recorded Macro from the NPP main menu and save your macro with a name. You can also give this macro a keyboard shortcut for ease of use later.

How to add #uv at the end of your selected text

1. Repeat steps 1-2 of the list above
2. Set the fields of the find/replace form as follows:
   • Find what: -> (?s).*
   • Replace with: -> ${0}#uv
   • Wrap around -> checked
   • Search Mode -> Regular expression
   • In selection -> checked
3. Repeat steps 4-7 of the list above
