Force Exit Crashed Program

When my program got crashed or not responding I usually end its process through Task Manager.
But, because of some cases --e.g. viruses, or registry restriction-- my Task Manager cannot be accessed by pressing Ctrl + Alt + Del.
Tips:
Type in Command Prompt or Run dialog : taskkill /im processsname.ext /f and press enter.
Replace processname.ext with the name of your program, it could be be firefox.exe for Firefox, or winword.exe for Microsoft word.

Hard Refresh

Sometime you have to 'hard refresh' the browser to view new changes in your website contents. Holding Ctrl key at the same time you hit the Refresh button or when pressing F5. Works on all browsers.

Paste and Go

Paste and Go (Ctrl + B) is the one of Opera features, doing this will paste a links you have copied into the address bar and immediately execute the link. Pressing Enter is no longer needed.

Show only this frame

Firefox browser will let you tho show only the frame content sources.
To do so, right click on the frame and choose Show only this frame. You know that some people hate framed website, including me ;)

Mouse Gestures on Opera Browser

Mouse Gestures is currently only available on Opera Browser. It's useful to navigate faster by letting your mouse movements control the navigation. Browse between pages, open and close windows, and navigate links with quick mouse movements.

Tip:

Hold down the right button at the same time by moving your mouse to the left will bring you to the previous page.

Another Tips of Open in New Tab

This is assume that you're using Firefox Browser.
You can do double click on an empty space on the Tab Bar, it will open and empty New Tab. I'ts easier than pressing Ctrl + T since your hand is far away from keyboard.

Also try:
Middleclick on a Bookmark on your Personal Toolbar will open your bookmark in a New Tab
MiddleClick on a folder that will open all the bookmarks in the folder in a new Tab (not recommended if you have numerous bookmarks)
Hold down the Shift/Ctrl and right click on the "View Image" or "View Backround Image" to open the image in New Tab or New Window.

quick google search (again)

Finding some words / phrase when browsing? Wanna search another resource related to that words / phrase in Google? Select these words / phrase using your mouse, right click and select menu 'Search Google for "your selected words/phrase"'. Nice, you don't even need to copy and paste it in Google search box.
note : Firefox only (again)... :)
