drush -y en devel
drush vset devel_page_alter 1

To enable the broader set of modules, it would be great to have these wrapped in a couple drush commands.

Enable

drush -y en enabled_modules views_ui xray

To indent a set of eight lines in vim, from the first one, in normal (esc) mode:

8>>

To indent a curly braces block, go to a curly brace and:

>%

To mark and indent (using 'm' as the marking letter, the first m is the marking command):

Enter mm at the top of block to indent, go down to the end of what needs to be indented, and type >'m

You may know about ctrl+shift+R for reverse case-insensitive search (or whatever it stands for) and that is still useful if you remember one very unique keyword from the middle of a command.
