I don't know if something has changed recently in Visual Studio 2015 but before I was able to press ALT + UP ARROW KEY
or ALT + DOWN ARROW KEY
to move lines in code up or down and now it does not do anything.
I went into Tools > Options > Environment > Keyboard
and I cannot find anything like in the past called
ProjectandSolutionContextMenus.Item.MoveUp
or
ProjectandSolutionContextMenus.Item.MoveDown
Also here in the list of VS2015 I don't see that option: http://visualstudioshortcuts.com/2015/
How to achieve this?
The commands you are looking for are Edit.MoveSelectedLinesUp and Edit.MoveSelectedLinesDown. Shortcuts for them should be defined in the Text Editor context.
