How to remap ctrl+arrow keys to move word to word for mac
You can change the keyboard shortcuts for changing spaces from System Preferences:
Then create ~/Library/KeyBindings/ and save a property list like this as DefaultKeyBinding.dict:
{
"^\UF702" = moveWordLeft:;
"^\UF703" = moveWordRight:;
"^$\UF702" = moveWordLeftAndModifySelection:;
"^$\UF703" = moveWordRightAndModifySelection:;
}
You have to quit and reopen applications to apply changes to DefaultKeyBinding.dict.
