Gvim editor tutorial: moving back trough changes

The changelist remembers the position of every change that can be undone. 
You can move back and forwards through the changelist using the commands:
g;
g,


You can view the contents of the changelist by running the command:
:changes

Vim also maintains a jumplist, 
remembering each position to which the cursor jumped, rather than scrolled. 
You can move backwards and forwards through the jumplist with the commands:

ctrl-O
ctrl-I

You can view the contents of the jumplist by issuing the command:
:jumps

you can follow the keyword  under the cursor with the command (ctags required):
ctrl-]
