General Tips and Tricks

How to get permalink of a post on Facebook?

So, you want to point your friends on facebook to a specific post but you can’t find a way to share that post with them via a button or link in the vicinity of that post. Or, suppose you are taking part in a contest on a company’s facebook page or group and you want to deliver maximum likes or comments on a certain post of you there. Then you would certainly want yourself to be able to give your friends the exact URL of that post. Unfortunately, I don’t find any clearly available option to get such a permalink for any post on facebook. Whenever you get a notification about a new comment or like on a post you are subscribed to and you click on that notification then that is the permalink that I always wished I could get without going through the notifications. Luckily, I found the following hidden trick to get it. The permalink of any post on facebook is hidden under its time stamp. So to get the permalink of any post, click on its time stamp reading “x hours ago”, “x seconds ago”, “a few minutes ago” etc. depending on the time passed since that post has been posted as shown in the following screen shot.

  3. Click on the “Installation” tab.

How to select a vertical block of text in Microsoft Word 2007

I was reading a book on Microsoft office Word 2007 when I came across this tip. It was a new piece of information for me so I thought I should share it with you all my friends. The tip is that if you click and drag with your left mouse button while holding down the Alt key on your keyboard, then you can select a vertical block of text in your document. For more explanation, please see the following screenshot.

Isn’t it amazing? However, a little bit of care is required in making such a selection because if you simply Alt+Click a word in MS Word then it launches the Research task pane instead of starting a selection. So, follow the following steps in a sequence to accomplish this task without any hassle:

  1. Press and hold down the Alt key on your keyboard.
  2. Left click in your document where you want the upper left corner of your selection and hold down the mouse button.
  3. Drag your mouse to the point where you want the lower right corner of your selection.
  4. Release the mouse button and then release the Alt key.

You can, however, start the selection from any of the four possible corners and end it on the opposite one.
