I installed power tools and that seems to have disabled moveline. The functjionality in power tools does not work in html, so i deinstalled it. But now even after deinstall and reinstall of moveline, i cannot get it to work.
Check to see which shortcut keys are assigned to the Tools.MoveLineUp and Tools.MoveLineDown commands: In the Visual Studio main menu go to Tools -> Options -> expand Environment -> select Keyboard. In the "Show commands containing" box type Tools.MoveLineUp or Tools.MoveLineDown. Assign the correct shortcut key if no shortcut is defined.
If the correct shortcut keys are already assigned, another command may be using the same shortcut keys and interfering with MoveLine. To check this, click in the "Press shortcut keys" box and press "Alt+Up Arrow". This should list all the commands that use that shortcut key. You can then remove the shortcut from those commands that are interfering. Do the same with the "Alt+Down Arrow" shortcut.
I hope this solves your issue.
