The following editor actions work in a mode opposite to the one established by the Use 'CamelHumps' words setting:

  • Move Caret to Previous Word in Different "CamelHumps" mode
  • Move Caret to Previous Word with Selection in Different "CamelHumps" mode
  • Move Caret to Next Word in Different "CamelHumps" mode
  • Move Caret to Next Word with Selection in Different "CamelHumps" mode
  • Delete to Word End in Different "CamelHumps" mode
  • Delete to Word Start in Different "CamelHumps" mode

For example, If the check box is selected, the action Move Caret to Next Word in Different "CamelHumps" mode moves the caret to the end of word; if the check box is not selected, then the caret moves to the next CamelHump.

These actions have no default keyboard shortcuts, and are not included in the menus. Thus, they can be invoked by pressing Ctrl+Shift+ACtrl+Shift+ACtrl+Shift+ACtrl+Shift+ACtrl+Shift+ACtrl+Shift+ACtrl+Shift+ACtrl+ICtrl+Shift+AShift Command AShift Command ACommand 3:
