The best way to become faster at using Revit is to trigger more commands with the keyboard. This is a trick that anyone using AutoCAD learned years ago. You can just hit a few keys much faster than you can find a little button with your mouse. Plus, you don’t have to wait for the interface to catch up with (yes, I’m talking to you, Mr. Ribbon!)
Over the past few years, I have put together a pretty comprehensive and fast set of Revit keyboard shortcuts. As I am right-handed and will generally have my right hand on the mouse, these shortcuts are set up around the fact that my left hand will be sitting around ASDF on the keyboard. Most of them are based on two-character shortcuts, and they generally reflect the first letters of the command they are triggering.
Some of them are a throwback to the old AutoCAD days (you will know them when you use them 🙂
