Hammer on's, pull off's and string bending - from Squidoo:
Hammer on: A hammer on is indicated by an H on guitar tab.
What this actually means is to fret a note (usually with the first finger) strike the string then slam your finger on the adjacent fret (higher in pitch) without repicking the string. This allows to play passages of music very quickly.
Pull off: A pull off is indicated by a P in guitar tab.
A pull off is a hammer on in reverse, they are a little harder to play, but with practice you will get them down in no time. You start a pull off by having two fingers on the fret board. You will strike the string then literally pull the finger away from the string without repicking. When playing a pull off dont just lift your finger off, actually pull down and away so that the note will ring.
String bending: String bending is shown as an up arrow on guitar tab.
Most string bending is done by having your first 3 fingers on the string and pushing the string either up or down to raise the pitch. String bending is a great compliment to solo's. Listen to Jimi Hendrix and blues players to get a good feel of what string bending is all about.
