On the keyboard? Stay on the keyboard. On the mouse? Stay on the mouse.
Every time you switch back and forth your brain has to remap itself to new processing areas.
For example, if you are editing web pages:
1. Start out in your text editor. (Have FireFox already open and viewing the same file: File/Open File)
(Using your pinky finger on the CTRL or ALT key so you can do these one-handed)
2. CTRL s – Save
3. ALT TAB – switch to FireFox
4. ALT r – Refresh the web page to see your changes
5. ALT TAB – switch back to your text editor (Hit TAB multiple times to jump to other open applications.)
6. Edit the code in your editor.
7. CTRL s – Save your changes and loop around again.
Other very help hot keys (to keep your brain from switching tracks every few seconds)
CTRL a – Select all information (without having to scroll down)
CTRL c – copy the selection or CTRL x – cut the selection
CTRL v – insert the selection (think of the v as a wedge inserting at the cursor position)
And my all time favorites:
CTRL z – undo (walk backward through your changes)
CTRL y – undo your undo
All of these work on all operating systems which makes them especially powerful.
Remember the mantra: On the keyboard? Stay on the keyboard. On the mouse? Stay on the mouse.
