I still have problems in new v0.61:

1. When trying to change shortcut for [previous file] from PgUp to backspace , I get a warning that backspace is already assigned to [previous file] and it is not changed.
Backspace is of course not assigned to [previous file], but it is assigned to [Up].

2. I then tried to change the shortcut for [Up] from backspace to Shift+Up and got the same incorrect message that Shift+Up is already assigned to [Up]. However, in this case the shortcut was changed.

3. After changing the [Up] shortcut, I was still not able to assign backspace to [previous file] (I got the same error message as in 1.)

I saved my 3 custom shortcuts to a file. Sometimes after I load this file, one of the shortcuts may not work although they are loaded properly, e.g. changes Shift+L to Shift+Left[arrow].
Reloading and/or manually changing back and forth usually make them work.

So you are able to change them???
But at a next start, some hotkeys are missing??
