How to enable quickswitch

With respect to bunny hopping, in the old GoldSrc games (Counter-Strike, TFC, HLDM) you could gain significant speed when jumping and strafing (moving sideways, e.g. with A and D) Begin by moving forward and jumping. While in mid-air, stop holding forward (W), and only strafe with either A or D. When you hit the ground, immediately jump. You continue to move faster and faster without ever hitting forward (W), but only if your jump timing is nailed down and you strafe only. Some people will bind +jump to mwheelup and/or mwheeldown and just roll the wheel to try to hit the timing.

As mentioned, I'm unfamiliar with "micro sniping", but a common tactic when using scoped rifles is to quick-switch weapons to avoid spending any significant time scoped. To do so, line up a shot with a rifle, unscoped, then quickly mouse2 to scope, mouse1 to fire, then 2 to switch to your sidearm as fast as possible. Done well, the switch is virtually instant and you can begin firing rounds from your pistol almost immediately. This allows you to finish off your target(s) if need be, without wasting time scoping or waiting on the delay to fire your rifle again.
