Extra options modal: Ability to switch easily between shell commands

[Taitava]

Method 1

Considering the extra options modal view of a shell command, I think I could add some up/down arrow buttons in the modal that would switch to the previous/next shell command, respectively. The best place for them would be next to the closing x button, but I don't know if I'm able to add stuff there.

Edit 2022-07-20: It's so hard to add stuff to the place I planned, that I decided not to implement this at least now. Can see if this can be done later.

Method 2 (added 2022-07-20)

Hotkeys Ctrl/Cmd + Up/Down to switch to previous/next shell command.
