They allow you to jump to (f/F) or one-character-shy-of (t/T) the
Nth (default N=1) match of the subsequent letter. So in this
paragraph, if I'm at the beginning (on the "T" in They), typing
"f(" will go forward to the first paren around the "f/F". Typing
"3t-" will go to the "y" in "shy". The F/T versions move
backwards instead of forwards as f/t do. It's particularly
powerful in concert with commands like "d" or "c". Often I want
to "delete up to the next character {c}" such as in code, so I
might use
dt.
to delete up to (but not including) the next period.
So rather than pressing "l" a whole bunch of times to move right
a bunch, or even pressing "w" a bunch to jump by word, if there's
a unique character (unique chars may be more assessable in code,
but certainly eye-ball'able in prose), I'll just use the
"f/F/t/T" suite to jump to that unique char in one motion rather
than potentially overshooting.
The ";" and "," motions simply repeat the previous f/F/t/T motion
in the same/opposite direction respectively. A small caveat: if
you issue "tX" to move up to the next "X" character, hitting ";"
alone is a NOP because the next X is the character after the
cursor, so it moves forward one to that character and then backs
up one, leaving you where you were.
