Keyboard shortcuts that save time

When you have multiple windows open, it can take alot of time to switch between the various windows with the mouse, especially when doing small copy-and-pastes. Try the 'Alt+Tab' keyboard shortcut to switch between the windows faster.
Hold down the 'Alt' key and press the 'Tab' key to popup a list of the active windows. Each press of 'Tab' will switch to the next window.
