<heheheh> Yep, that's it exactly. So far as I know, there are only 7 *REAL-WORLD* (as opposed to pure bullshit media/anti-gun hype) firing modes:
Single-shot = one trigger pull makes one bang, then manually reload the weapon before you can shoot again. EVERY muzzle-loader is a single-shot gun. There are also a good number of (reasonably-)modern breech-loaders that are single-shot.
Semi-auto = one trigger pull makes one bang. Repeat until magazine is empty, you have a round fail to fire, or have a mechanical failure of some type. Then either reload, manually cycle the action, or fix the malfunction (if possible) before you can start firing again.
Single-action revolver = Pull back hammer, pull trigger. One bang. Repeat as many times as there are holes in the cylinder, then reload. A very few, very old, very scarce nowdays models may require manually rotating the cylinder between shots.
Double-action revolver = Pull the trigger, get one bang. Pull it again. One bang. And again. One bang. Repeat until you run out of whatever capacity your cylinder has. Reload and start again.
Burst mode = one trigger pull makes <insert round count that particular gun is set up to produce> bangs. Repeat until mag is empty, reload.
Full-auto = One trigger pull-then-hold goes bang over and over again until the trigger is released, the magazine runs dry, or a mechanical failure (perhaps you've shot so many rounds the barrel melts...) or similar issue stops the fire/eject/load/fire cycle.
Continuous fire = Gatling gun, the A-10 Warthog's GAU-8 Avenger, the M-134 Minigun (AKA "The gun Jesse Ventura's character uses in the movie Predator") etc - Hit the switch or turn the crank - it keeps firing until you stop turning the crank, release the switch, the ammo supply is gone, or there's some sort of mechanical failure, whichever comes first.
