i had the same issue with the new msi gaming laptop i bought.
the end at my n1 doesnt work sadly, so i have to use the end under fn. (which also happends to be my pgdn key)
was struggeling with it for the longest time since my previous laptop didnt have the problem that i had to use that specific end key in the corner.
now im just struggling to quickchange weapons cause all the buttons are so far spread from eachother hahaha
Glad you found the solution tho, im out here struggling with you mate ;D
