Hi eliav,
Welcome to the world of X-Plane.
I don't agree with tyler.
At the time of your posting I went searching for the list of keyboard strokes I had previously found through Dr Google and was not successful in my search and subsequently did not respond.
Since tyler's response I have now found a comprehensive keyboard stroke listing for flying without a mouse. The link can be found at http://forums.x-plane.org/index.php?/files/file/21972-x-plane-10-pc-keyboard-cheat-sheet/ Although it gives a listing for XP10 I have been lead to believe it works for XP11.
I know the XP10 version has a number of keyboard key strokes available as part of the use of the software and are generally found in the software drop down menus. Again, I would be surprised if it does not work for XP11.
By the way, the Xplane.org site provides a lot of information just for X-plane users not just as a forum but for other "stuff" s well including freeware aircraft. Trawl through the web site.
If you have any hardware from your FSX days then it should work with X-Plane.
Hope this helps.
Glenn
