Binding symbols that are entered by holding shift also need the `<Shift-` prefix in the config

[SeerLite]

Example (on US QWERTY):

<plus> = zoom 1

should work. But since the symbol can only be produced by holding shift, it's necessary to add Shift as a modifier:

<Shift+plus> = zoom 1

There cannot be a non-shifted version of plus on this layout so it's hard to figure out what's missing. I think the input/binding system has to be reworked so it behaves like other programs.

Thanks
