handles absolutely nothing key-wise, as it should have
been in the first place probably
- Allow editing of special mode keys
- Fix accelerator input, so that arrows can be bound
at will. This was a stupid typo (mods instead of mode),
sigh.
- Remove all the legacy widget accelerator cruft.
- Bind actions to non-widgets.
- Allow page up, page down action. For now, page size is
not customizable (usually 50% of the screen). However,
we don't bind fit width or fit size to anything anymore.
This can be overridden.
- Fix problem reported by IcyAirs, where the "fixed location"
mode for folders did not work properly.
- Allow disabling an accelerator and inputting the escape
key (normally, the escape key cancels the accelerator
input).
