Well here is the problem my right mouse click works for almost everything except for equiping spells on right hand also in some menus it doesn't work which would not be bad if I wasn't playing as a mage.I even tried with other buttons,only E worked but again if I sellect spell with E it puts it in left hand and wepons always in right.Any suggestions what to do?

Assign it a number in favourites then press the number twice.

Left click a spell to get it into the right hand? You can also double click (both mouse buttons), and then right click to make it only in the right hand, but yeah, left click right hand, right click left hand.

No left click lecft hand right click doesn't respond at all I can try that with numbers

I can't assaing anything its supposed to be shift+numer right?

Try using default keymap.

No shift. With the favorite list up in game world hover over the one you want and just press the number you want assigned to it.

As far as putting spells in right hand the only way I've found is this:

Unsheath weapon so you can see hands.
Press a hotkey for a spell. Shows up in Left hand.
Press that hot key again, spell is now in both hands.
pressing another hotkey (other spell, torch, shield) puts it in left hand leaving other spell in right hand.

Problem solved keybiding worked I did it in a wrong menu its supposed to be done in favourites menu and not in magic menu my bad.

none of my mouse buttons work in menu(when you press tab to go to items ) or favourites?!?
