Marks
Any position in the text may be marked using "mx" where x is a character from a-z. You can jump to a mark with "`x" and to the begin of the line where the mark is set with "'x". Marks are local to the editor in which they are set.
Uppercase marks, which should mark a position in a specific file, are not supported yet.
There are three special marks: "'", ".", and "^". "'" marks the position from which the last jump was made. "." is where the change was made . "^" marks the end of the last insert operation. There is also a mark "`" which is the same as "'".
All marks are motions and can be combined with operators.
