Bitbucket Cloud comes with keyboard shortcuts you can use to quickly access pages and features. To use these shortcuts, the Bitbucket page must be active in your browser (Firefox, Internet Explorer, Safari, etc.). So, for example, in Firefox to make a page active you click its tab. Once you have an active window you are free to use any of the shortcuts. Most shortcuts are a combination of keys where you press one key and then the next in sequence, such as g then i to go to your inbox. Some shortcuts are a single key press, such as / (forward slash) to put your cursor in the search field.
To view a list of keyboard shortcuts for your current page: Press <?> (question mark) on your keyboard.
To disable or enable keyboard shortcuts: Go to avatar > Bitbucket settings. From your Account settings, you can deselect or select the Enable keyboard shortcuts option.
