Well this might help someone in the future since i needed to do this to move on in the game myself
This comes from Rockstar Games -Max Payne3 Tech Support Website/Page
Question: I am in the burning building in Chapter 6 of Max Payne 3 for PC. I've just pushed over a cabinet. When Max climbs on top of it he stops moving. I'm unable to pass this area. Help!
Answer: If you are using a mouse and keyboard, please check the gamepad controls from the options menu. If the "southpaw" option is enabled, please disable it for this section of the game. (Well i was useing a controller but doing this fixed me being stuck so i can now move forward in the game )
PS: i agree F2 does not activate but i never seem to run ot of bullets so it is just one of MAF's (hidden easter eggs to see if we are
smart enough to know it is on when it shows it as off )
