Triple-click to select paragraph
To select an entire paragraph, such as this one, left click on it three times. This works in IE and Firefox (but not in Opera, however it might work in others like Safari or Konqueror). From there you can press CTRL+C to copy and paste into Notepad, Word or wherever you wish.
CTRL+F5 to force-reload
You’ve heard the phrase a million times, "Clear your cookies/cache and restart browser to view X properly." Most of the time the same thing can be done via a CTRL+F5. The F5 is to refresh the page. When used in combination with CTRL it overrides the cache and loads everything as new.The CTRL+F5 function to the best of my knowledge universally does the same thing across all web browsers.
CTRL+H to view history
It’s true you can view browser history simply by examining the address bar, but if you want to see where you’ve visited by day, most visited and so on, you need look at the browser history. This is done in IE or Firefox via CTRL+H. This opens up a sidebar with all your history in it.
Jumping to tab by number
Each tab you have open in your browser is assigned a numerical value. You can easily jump to the first 9 by pressing CTRL and the corresponding number.
For example, if you have three tabs open and want to jump to tab 2, press CTRL+2.
F3 to search again
Searching for text on a web page is easy. Just press CTRL+F and type what you want to find. This is (as far as I’m aware) universal across all web browsers. When you do this, the first instance of what you were looking for is found.Most people use clickable arrows to continue searching for the same text. However it’s much easier just to press F3 if you want to keep searching the page for the same text. To search in reverse direction, use SHIFT+F3.
