[Feat] wxGUI/history: Keyboard shortcuts for Copying and Deleting Commands

[lindakarlovska]

Is your feature request related to a problem? Please describe.
I want an easy way to delete and copy commands, including multiple selections.

Describe the solution you'd like
When one or more commands are selected:

• Pressing Delete will prompt a deletion confirmation.
• Pressing CTRL+C will copy the selected command(s) (if more - separated by comma).

I am often surprised by software that uses CTRL+D to delete, (as the delete or backspace keys exist for that). Most of the software, at least that I use, would use ctrl+d to duplicate.

Good point @echoix, the delete key is more appropriate. I edited it in the Issue description.
