Bring back keyboard shortcuts for custom fields

The old instance of Jira allowed the user to use keyboard shortcuts on fields. This made it so that the user could edit any field in a Jira card using the keyboard. Now, on the cloud instance, a user cannot edit custom fields with keyboard shortcuts, so they need to use the mouse to navigate to fields, type their response, click away, then the field saves. When there are multiple fields of this nature, it significantly increases the amount of time it takes to administer one card – meaning that administering an entire sprint's worth of work takes much longer than it did on the old instance. Please bring back keyboard shortcuts for custom fields so users do not have to go between the keyboard and mouse when editing cards.
