Windows : Remove Text Formatting When Pasting To Outlook

This was just annoying me.

I am working with a php webpage and when I copy paste into Outlook it was also copying the font and highlighting.

The fix:

  1. Select the text
  2. Ctrl + Spacebar

This is a nice link to other Outlook Shortcuts:

Windows Search ..

I know this is unixtips.net but I ran into an annoying issue after upgrading to Windows 7. It seems that after my upgrade I was no longer able to search the contents of my .txt and .log files that were on my PC.

Here is what I did.

Start -> "Search Programs and Files" -> Indexing Options -> Advanced

On the File Types Tab.

A bunch of file extensions will show up here.

Scroll down and choose txt .. In the “How should this file be indexed?” Make sure you choose “Index Properties and File Contents.”

Go through and check text too.

For .log files you can “Add new extension to list” and make sure you choose “Index Properties and File Contents.”

Thats it .. after indexing is complete you are golden.

Sorry no screenshots.
