Change Ctrl+Arrow and Ctrl+Shift+Arrow to jump/jump+select a single word rather than the whole line?
Create ~/Library/KeyBindings/ and save a property list like this as DefaultKeyBinding.dict:

{
  "^\UF702" = moveWordLeft:;
  "^\UF703" = moveWordRight:;
  "^$\UF702" = moveWordLeftAndModifySelection:;
  "^$\UF703" = moveWordRightAndModifySelection:;
}


Then quit and reopen applications to apply the changes.
