Tips & Tricks
1. Change the font size
While holding the control key, move the scroll wheel on your mouse either up or down. This trick works while being focused in either the read or write area.
2. Insert line breaks
If you want to have a message that spans multiple paragraphs, just hold shift and hit enter. You can add as many new lines as you want to create.
3. Bold Text
To write something bold, you can use an asterisk before and after the word. For Example *SIDHANT*
4. Italic Text
To use italics, use an underscore before and after the word. For Example _SIDHANT_
5. Switch windows
Hitting tab will cycle through open windows. It will select minimized conversations, to expand them just hit enter. If you just want to cycle through IM’s and don’t care about the buddy list, control-tab will do that and will automatically expand a minimized conversation if you settle on one.
6. Invitation Tips
You don’t need to say Yes or No when someone wants to add you as a friend; you can simply ignore it, the request will go away. (On the other hand, someone with whom you chat often will automatically turn to be your friend, unless you disable this in the options).
7. Show Hyperlinks
You can show your homepage or blog URL simply by entering it in your away message (at the top of the main window). It will automatically turn to a link visible to others.
