If you’re trying to get around documents in VIM using a Mac keyboard, you may feel fairly stumped without a page up and page down button. But you need not be!

VIM has an extensive set of commands, including moving backwards and forwards through a document a page at a time. They are logically named too – Ctrl+F will go forward a page and Ctrl+B will go back a page.

Sometimes, it’s easier to create an alias when working with the Unix command line. Having to create these every time seems to defeat the point of having a short alias though. Luckily, you can make them persistent.

Lets assume that we are using a user called mike. We need to be in our home directory.

cd /home/mike

The .bashrc file should be in there, but hidden.

ls -a

You should be able to see it listed. Now lets edit it.

vim .bashrc

And add a command in, for example, to save our usual CVS update command.

alias upd='cvs -q update -P -d'

Now save and exit. After that, every time you log onto the box you can use the upd command to run the CVS update.
