Ok..I am surprised nobody started a thread for this, as these are the invaluable tricks necessary to making level creation a lot more quick and easy. I only know two at the moment, having pulled them from searches of the various threads here. My hope is that people will continue to add to the list as time goes by, and anyone who performs a search for "shortcuts" will pull up this thread and find all the goodies in one spot !!
1) Ctrl M - used to match your layer edge vertices, a HUGE time saver that will help eliminate problems where layers merge and their vertices don't match. Since they have to match exactly, his little shortcut is invaluable, and will turn hours of work matching your vertices into minutes or seconds instead.
2) Control left click on a layer - this will select all the layers in the associated group of layers, so you can work on multiple layers at one time. (ie: select multiple layers & ctrl-M to match the layer edges.)

For some reason one of the most used is omitted.

This list could use a little ordering to make it easier to use but I hope someone might be able to identify the posters if it's kept in orginal format and order.
If you know of anymore useful keys please list them
