Hello and thanks for reading =)

I currently have a RST Omega TL suspension fork ( came together with my GIANT bicycle last year) and till now,I have no idea how it works. I would greatly greatly appreciate it if anyone (i mailed RST but they didnt reply =( )could tell me what the knobs on top of each fork mean :

On the left fork (left fork being the fork on the left if im sitting on the bike facing forward), there's this knob which has the word RST in the middle, and an anti clock wise arrow labeled ( - ) , and a clockwise arrrow labeled ( + ) . Could someone kindly tell me what happens if i turn anti clock wise (-) or clock wise (+)

On the right fork, there's this knob which has the word "PRESS" in the middle, and an anti clockwise arrow labelled (L) and a clock wise arrow labeled (S) . COuld anyone again, kindly tell me what happenes if i "PRESS" the knob and turn it anti clock wise (L) or clockwise (S)

Also, if i turn the knob on the left fork, would the effect be felt on the right fork too? The same goes for the knob on the right fork, if i "PRESS" it and turn it, would the effect be felt on the left fork too?

Please do kindly reply as I keep seeing these knobs when i cycle and have no idea what they do..and im scared to do anyhting to them as im afriad the bike might just spoil in my hands.. Ive tried reading the manual but it had nothing on two different knobs. Please do help me.

thanks thanks thanks thanks a million thanks.
