Not sure if anyone knows this or anyone cares. I use Outlook for my email and Alt+S will send the message for you. I guess I was so used to doing that, when I posted in a vBulletin forum one day, I must have instinctually hit Alt+S to post/send it. The next thing I knew, it posted the message. It is a nice shortcut so you don't have to scroll down and click the submit button and if you are used to doing it already from Outlook/Outlook Express it is a no brainer.
There are lots of shortcuts in vBulletin... if you mouse over links or buttons, it will tell you the shortcut. Some I use... ALT+1 = main page ALT+2 = new posts ALT+4 = search ALT+X = go advanced
lol, and here I thought I found some cool trick. LOL. Thanks man. I am a bit afraid of Alt+X, I will wait a while before I try that out.
