Is there a shortcut or a command to select word under cursor in Sublime Text or Atom? I want a replacement for double-click. So I could press shortcut instead and get selection on a current word and start typing to replace it or get in quotes etc...
command+d on OSX
control+d on Windows/Linux
You can find all the default keybindings by going to Preferences > Keybindings - Default
and perusing the list.
