Hello,i’d like to know if this feature has been added,and in case it hasn’t been improved,i’ll make a feature request.
Multiple selection feature exists in Cloud9 for several years.
Use ctrl-alt-arrow keys, or ctrl-alt-mousedown and alt-mousedown
It is also possible to change ctrl-mousedown similar to sublime by disabling
usersettings>language>use command click to jump to definition
Let us know if you see any way to improve this feature!
