# Put this function to your .bashrc file.
# Usage: mv oldfilename
# If you call mv without the second parameter it will prompt you to edit the filename on command line.
# Original mv is called when it's called with more than one argument.
# It's useful when you want to change just a few letters in a long name.

tabindex is an HTML core global attribute.

With it you can control in what order the elements get the focus, when the user presses the TAB key. You can also prevent an element to gain focus through the TAB key.

Typical example:

1. We have a login form
