Skwire I think we can close this post.
I try in the pspad forum and with a macro is possible to group the way i wanted :
this is the macro in the pspad context (for more information go to pspad forum english section)
you can record a macro and call it repeatedly,
cf. a similar task in a previous thread:
(I'll just update your formatting to the needed steps.)
Place the cursor at the beginning of the text.
Tools: Macro: Start/Stop recording (Ctrl+F5)
and perform to following steps (key presses):
Then press Ctrl+F5 again and enter the macro name like asterisk_3_lines
Then go to
Tools: Macro: Macro manager
select number_lines_1_2 and click play x times
and set the appropriate number depending on the number of lines.
If you set more macro runs than necessary, you will have to correct the extra asterisks in the last line.
(If you have "Extended Home/End" options active, you would need to take that into account (Program settings: Editor (part 1): [x ]Extended ...)
Goes well with those instructions.
I am using intensivily too the Contro Text Tool
