This question asks about the end key but the answers give no examples: http://superuser.com/questions/60052/what-key-works-like-end-using-a-mac-with-synergy If they had, I am guessing that they would likely have run into this problem. Adding lines like the bottom two of this: section: options keystroke(End) = keystroke(Control+Right,myiMac) keystroke(Home) = keystroke(Control+Left,myiMac) to my synergy.sgc in MyDocuments on the winXP machine would work but causes the keys to stop functioning on the winXP machine. Unacceptable. I next tried a compromise: keystroke(End) = keystroke(Control+Right,myiMac); keystroke(End,myPc) keystroke(Home) = keystroke(Control+Left,myiMac); keystroke(Home,myPc) Expecting that to broadcast the keystrokes to both machines regardless of which one was the Active Screen. That and many other variations did not work. What am I doing wrong? Has someone actually done this?
