Slap/pop
Thumb-slaps and finger-pops (usually only on basslines) don't have a standard notation in TAB, but I use a '.' (full stop) before a slap and a '+' (plus) before a 'popped' note, as in this octave pattern:
G-------------------------
D----+3----+3----+3----+3-
A-------------------------
E-.1----.1----.1----.1----
That's about it - if you have any problems reading my tablature which aren't covered here, consult a proper guide (the links page is a good starting point).
