Subject: [PATCH] Fix display of `+` between modifiers on linux and windows
 (#24173)

Regressions in #24024:

* `+` was no longer included between modifiers and key
* Multi-character keys like "control" were displayed all lowercase,
whereas before they were all uppercase like "CONTROL". Now they are
capitalized, so "Control".
* Brings back icon for tab key.

Release Notes:

- N/A
