Short description of error
Shortcuts with accents like ` or ´does not work on serveral languages.

I guess every language using accents have the same problem, cause it is a special char that needs another key after shift-accentgrave. Like shift-accentgrave gave nothing pressed until another key, for example a -> à. Or space for a ` alone.
So the default shortcut "shift `" in the keyboard map for "View Navigation (Walk/Fly)" does not work.

A accents shortcut also cannot be set in the preferences, for example a shift+` gives a "shift ]",
a shift+' gives a "shift /".

Changing the interface language to english, does not affect this.

Exact steps for others to reproduce the error
Reproduce on a system with a language that uses accents.

• in preferences/keymap choose a function like (walk/fly) an try to set it to "shift `"
• the key is change but it does not show "shift `", it shows "shift ]" (on a german language system)
• activate walk/fly dont working with "shift `"

I tried "'" instead of "`" or "´" and it is working for that. But it displays also the wrong key in the preferences/keymap with "shift /".

shift ' -> displays shift / -> mapped to shift '
shift ` -> displays shift ] -> mapped to (didnt find it/unmapped)
