ME3 LE: No button on my keyboard skips dialogue

[archromat]

ME1 LE, ME2 LE: both can skip dialogue with space bar.

However, ME3 LE, no button skips dialogue and it's driving me nuts.  How do I fix it so that spacebar also skips dialogue in ME3 LE? Yes, I tried reinstalling; it didn't change anything.  

Someone please tell me they've solved this issue.

It should work with space bar.

Did you tried to repair the game?

(Origin > Game Library > right click MELE > Repair)
(Steam > Game Library > right click at MELE > Properties > Local Files > Verify integrity of game files.)

It works with the spacebar in ME1 and ME2 LE, but not with ME3 for some mysterious reason.  

It was my problem six months ago; I uninstalled it, reinstalled it, and had to verify the files because of a bug in ME2, but it still doesn't allow me to skip with spacebar or any other button.  

The problem persists; I tried to find out how to configure hidden hot keys in the game, but I don't know how to do it with ME3...
