You can no longer navigate forward and backward words with Option + Left or Right because RC has changed this to be used for non-disableable app navigation shortcuts. I cannot express how frustrating this is as someone who uses these hotkeys constantly and has never experienced an app that overrode those keys when focused on a text box. This should be reverted or given an enable/disable option immediately.

This also violates Apple's Human Interface Guidelines which states
"Use the Option key as a modifier sparingly."
"Avoid creating a new shortcut by adding a modifier to an existing unrelated shortcut."
