Keyboard modifier key icons

[DaniFoldi]

Describe the requested icon I'll start with the use case, since it makes it clear why I would like these icons to be added. On macOS (mainly), modifier keys are represented by symbols, when the shortcut is shown, like: ⌘+C, ⌥+⇧+X. command, backspace, windows-logo, arrow-fat-up, arrow-fat-line-up, arrow-line-right and key-return are already a part of the collection, and since the unicode characters are inconsistent, I prefer to use the icons when displaying shortcuts.

The missing icons are:

• ^-like for control
• ⌥-like for option
• something like the backspace icon in reverse for delete

Screenshots This is from the shortcuts tab of Google Docs, I find it inconsistent:

As for the icons to be added, something similar to the character would be the best option in my opinion.

Additional context Add any other context here.

I think we can swing an option and control icon. Thanks for the req!

Added option in 1.4! We'll get to control in the next round.

Added control in v2.0.0! Is the delete icon really a reverse backspace? I never noticed, but I guess it makes sense!
