The ability to customize the command palette’s keyboard shortcuts is now available to all github.com users in beta. Customize the keyboard shortcuts for opening the command palette in search and command modes in the Accessibility section of your user settings.
You can manage your keyboard shortcuts using the new accessibility settings page.
You can choose to disable "character key shortcuts". This turns off keyboard shortcuts that only use single characters like s, g c, and . (the period key). Shortcuts which make use of modifier keys like command and control are not affected by this setting.
This feature prevents accidental triggering of keyboard shortcuts. This is important for people who use a keyboard and for people who use assistive technologies like voice input.
Light and dark colorblind accessible themes are now available to all github.com users in a public beta. These themes swap colors such as red and green for orange and blue to make GitHub more inclusive for colorblind users. Navigate to the “Appearance” page in your profile settings to update your theme preferences.
