Multi-Cursor Support

[yorkshirelandscape]

Is your feature request related to a problem? Please describe.
In many modern text/code editors it is possible to spawn multiple cursors by hold a modifier key or two and pressing up or down. This is a tremendously useful feature and I am regularly bothered that CherryTree doesn't have it.

Describe the solution you'd like
Say you have a bunch of tabbed data and you want to delete a while column from the middle. You can delete the same column line by line or, with multi-cursors, you position your cursor where the column starts in the first row and hold, for example, Cmd+Opt and press the down arrow until you reach the last line. Now you can press delete to start removing the column, hold shift and move the cursor left or right to highlight a whole column, type the same thing in each line, etc., etc. I'm sure you've seen it before.

Thanks for making such a wonderful program. I only just discovered it recently, but expect I'll get a lot of use out of it.

Hey @yorkshirelandscape what you are asking is already there - you must keep Ctrl and Alt pressed and then select the column with the mouse

Hmmm... I'm having trouble doing it on MacOS. Is the shortcut supposed to be Ctrl+Opt or Cmd+Opt? I think I sort of got it to work once, but I haven't been able to reproduce it. Even then, would a purely keyboard-based implementation be possible? While I'm editing a document, I generally don't touch my mouse.

I can improve this in future but that will take some time as other features are in the queue.
It would be quicker to support using other keys on the Mac OS instead of Ctrl+Alt.
Anyway can you provide an example where I can see the keyboard only column mode feature?

VSCode has a very nice implementation. I think they refer to it as "Spawn Multi-Cursor".
