Removes some verbiage and arranges things consistent with other
settings dialogs.
Ideally we shouldn't litter UIs with shortcuts, tips, tricks,
self-evident or redundant descriptions, etc, so this can be
refined again in the future once there's an official way to expose/
customize keyboard shortcuts.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
