Don't you generally type with two hands? How often are you locking that this is a problem?

Everytime I get up from my desk, so once or twice per hour. Usually, I already have something in one hand, like a pad or cup of coffee.

My first thought would be to re-map Win+L with AutoHotKey or similar. Or, just press start, and arrow up and over to lock (lots more keypresses though).

I'm no good with macros, but the start+arrow idea is great. For me it's only one more keypress, but I can do it all with one hand. Funny thing is, I use that combo at home to put my home computer to sleep, because I don't leave that running in between sessions. Thanks for the tip that I should have known already!

You ought to retrain yourself, using the off hand modifier key is the correct way to type anyway.

Even if you don't type "correctly", it still doesn't seem like a big deal. I can't imagine anything easier than Meta-L.

Please elaborate.

It's very easy when you don't already have a cup of coffee in your hand on the way to a meeting.
