Accessibility issue: Single character key shortcuts

**Describe the bug**
A clear and concise description of what the bug is.

According to a recent accessibility test we've got the following issue reported back to us:

It is expected that if single-character keyboard shortcuts are present, then at least one of the following is true:

- Turn-off – A mechanism is available to turn the shortcut off

- Remap - A mechanism is available to remap the shortcut to include one or more non-printable keyboard keys (e.g., Ctrl, Alt)

- Active only on focus - The keyboard shortcut for a user interface component is only active when that component has focus.

**Additional context**
Any help to get any of the suggested fixes in place would be greatly appreciated :pray:

No files, tests, or entry points are named. Start by locating the user-interface handlers for single-character keyboard shortcuts and compare their behavior with the accessibility test criteria. Done means each shortcut can be turned off, remapped to include a non-printable key, or is active only while its component has focus.
