Invalid key code when mapping "-"

[tzemanovic]

Summary

Trying to map a "-" key to an action causes parsing failure.

Looking at the code, this is because '-' is used as a modifier separator and "minus" should be used instead. This restriction is not clear from docs alone, but imho rather than documenting it, it would be better to improve the parser to allow it as there is no ambiguity:

• without a modifier "-": on it's own it is clear we're binding to this char
• with a modifier "A--": arguably not as readable as "A-minus"`, but the middle '-' must be a separator and the '-' the key code
• invalid binding "A-": missing key code

Reproduction Steps

trying to map a "-" key to an action with e.g.:

[keys.normal.space.w]
"-" = "hsplit"

causes a failure

Bad config: TOML parse error at line x, column y

x | "-" = "hsplit"
