How carry out you get rid of shortcuts on your machine?

I recently got a cat + she loves walking on my laptop keyboard. today I took it out to work on top of my resume + found that I have a ton of shortcuts that make it impossible to work on thing. when I estate down the R key Run pops up, whenever I estate L, my personal locks, and thus on. this wouldn't be an issue if I had to press control + the message merely it's just the letter. I wring L and nothing else + my computer locks. help me please!
