Using a keyboard and no mouse
Go read the above article. PLEASE! As the writer (Jeff Atwood) says:
Here’s what I’ve observed users doing, over and over again:
1. Move the mouse to the username field.
2. Click the mouse button.
3. Type a username.
4. Move the mouse to the password field.
5. Click the mouse button.
6. Type a password.
7. Move the mouse to the login button.
8. Click the mouse button.
Every time I watch someone do this, a little part of me dies inside. And I see it all the time.
My colleagues KNOW not to let me catch them doing this because I have a compulsion to teach them how to do things quicker.
I once got so frustrated I actually asked my boss if he knew the shortcut for copying and pasting…! It was all down-hill from there!
