Browser Keystrokes! faster then the mouse
Keystrokes takes a little time to remember, but once you start using them you wonder why you didn’t before!
Zoom in/out/reset
Keystrokes:
Zoom in: CTRL-Plus key
Zoom out: CTRL-Minus key
Zoom reset to normal: CTRL-0 (zero)
There are times when you will be sitting at your computer for long hours and your eyes start to get a bit blurry. Even if you have a big monitor it’s a blessing to have a zoom function.
Jump to address bar
Keystroke: F6
You’ve clicked inside a Google or Yahoo search field and typed in a web address before, right? If you remember F6 then you’ll never make that mistake.
Open link in a new tab
Keystroke: CTRL-Click (hold down CTRL, click link)
Make use of the tab feature in your browser. This is one of the best usability features ever invented for web browsers; it’s far easier to manage tabs than multiple program windows. Use it, love it.
Switch between tabs
Keystroke: CTRL-TAB
Once you’ve got those tabs open you can switch to them with this keystroke (and back).
Closing a tab
Keystroke: CTRL-W
You’ll notice that you’ll be using your left hand a lot when doing the tab thing. You’ll be CTRL-TAB’ing about and need to close one every so often. Fortunately CTRL-W is just a few keys away from TAB to close tab(s).
Full-screen mode
Keystroke: F11 (F11 again to return back to windowed mode)
Need just a little extra space to read stuff? Sometimes you do. Pressing F11 will do just that.
Finding text on a web page
Keystroke: CTRL-F
There are times you’ll be confronted with a ton of text in a browser and need to find a specific word or phrase. CTRL-F allows you to do just that.
Note: In Firefox the input field will appear at the bottom. In IE it will open a mini-window which usually appears at the top left (or right depending where you last placed it).
