quick macros is a killer feature in devstudio i use all the time that not many other people seem to know about or use.  it's perfect for quickly automating repetitive changes.  for example if you want to take a large enum and turn it into a table of strings that's a lot of typing!  instead, using a quick macro just go to the first line, hit ctrl+shift+r then add your quotes, delete any enum prefix, ctrl+u after the first character to get some nice lower case, then finish it off with the cursor on the next line.  now just mash ctrl+shift+p and watch your productivity soar.  in some cases you can accomplish the same thing with regular expression find and replace, but i find it way simpler and faster to just do what i want done to one line then let devstudio repeat that for me.
