Long press on toolbar icons

[Roccobot]

Just like the long press on 'Paste' to just paste instead of opening the clipboard manager, it would be awesome to assign secondary functions to other pinned toolbar icons. It would be possible to have for instance 4 functions but only using 2 icon slots and saving a ton of space.

Meaningful examples:

Key	Tap	Tap + hold
ᐸ	Move cursor left	Move cursor to the beginning of the line
ᐳ	Move cursor right	Move cursor to the end of the line
⋀	Move cursor up	Move cursor to the first line
⋁	Move cursor down	Move cursor to the last line
📋	Copy selection	Copy all
⤺	Undo	Redo
⬚	Select word	Select all

They might be hardwired or customizable (I guess this would be much harder).

Use case
Keeping more useful icons on the toolbar without sacrificing too much space.

they all should be relatively easy to add and can be useful, thanks for the idea
same logic of the undo can be done for the redo button
would you mind if the move cursor up/down long press would be page up/down instead of first/last line?

Sure, just a variation of the same idea. I'm glad it is something that can be implemented, thanks! 🤩
