Hi all.Im kinda "new" to RF and i would like to ask how can i use the number buttons not the F's (F1,F2,F3,etc).

i dunno how but sometimes i did it accidentally and im wondering how can i do it?please respond THANK YOU

you can switch it from F's to #'s or #'s to F's... just simply press backslash "\"....
