The time is money. Also, if you always have to divide your time between mouse and keyboard, it slows you down a lot.
This is especially true when working on a laptop with an even slower pointing device.
Another arm's length answer is to learn some "handy" keyboard shortcuts. The top 9 are:
1. Fast Exit:
ALT - F4 exits the program immediately.
2. Scroll - do not click:
ALT - Press TAB to scroll through open programs.
3. Quick Select: Use
CTRL - SHIFT and use the LEFT/RIGHT/UP/DOWN ARROWS to move the cursor to quickly select an area of text.
4. Cut, Copy and Paste into Chase:
CTRL - X / C / V to cut, copy and paste selected text.
5. Undo what you did:
CTRL - Z undoes everything. (Repeat:
CTRL - Y, but this varies by program.)
6. Page - No Scrolling:
Use Page Up and Page Down in MSIE to save time fiddling with scroll bars.
7. E for Explorer:
WINDOWS KEY - E Open Windows Explorer. Use the up and down arrows to quickly move between folders.
8 Quick Rename:
F2 - Rename a file or folder in Windows Explorer.
9. Fly through the form:
TAB to move the form forward and SHIFT-TAB to move backward.
With a little practice, your fingers will fly across the keyboard like a shortcut pro.
It also saves a lot of time.
