Show Function keystrokes as part of the shortcut modes

[mawid6]

Hi! Great utility! This is an improvement request.

Summary: I would like for function key presses (F1-F12) to show up, when I have selected the shortcut modes.

Rationale - Why?

Function keys are keys intended to be used as keyboard shortcuts. They are in a way "one key keyboard shortcuts". They are not intended to be used to input letters or other symbols (there might be an exception, but I think we can agree this is the general case).

Therefore, it makes sense that they are displayed when used in the keyboard shortcut modes. This is also the way it works in other similar utilities.

Future, related additions

Yes, there may be more keys that could be part of this group. I think any keys that do not cause a visible entry, should likely be shown in this way.

• ESC/escape key is the same, for instance - it causes no visible letter or symbol to be created, but causes things to happen, even on its own without additional modifiers. Would like to have that as well, TBH.
• Navigation keys, e g PgUp / PgDn / Home / End. Same story, no input, but manipulates displayed contents or location of view.
