When I use the arrow keys on the number pad (NumLock off) the keys don't move the cursor. Instead they move the whole text window. The PgUp, PgDn, Home, and End keys work properly by moving the cursor, but not the arrow keys.
How do I make the number pad arrow keys work properly (just like the other arrow keys) when NumLock is off?
I'm using Android Studio on Ubuntu 14.04.
