Disable left/right keys to jump up/down

I use PyCharm with kids, who have limited text editing experience.

One thing I found really annoying (for them) is that if the cursor is at the beginning of a line and you (by mistake) press the left key, it moves up to the previous line. Similarly the right key at the end of the line moves down.

(They press this keys sometimes more than necessary.)

Is there a way to disable this feature? I would expect the left key to be ignored if you are at the beginning of the line, similarly ignore the right at the end of the line.

Thx!
