Edit toolbar buttons that depend on selection are (at least in NVDA) announced as Disabled when there is no selection, rather than being skipped over. Scrubbing may be started by shortcut even if the pointer is in the waveform, although the Status Bar messages don't refer to moving the pointer to Scrub. Different Scrubbing modes may also be started using shortcuts or the Transport Menu, but there is no keyboard interface yet to control scrubbing. However you can use the shortcuts respectively to set the left or right boundary of the selection at the playback or recording position ( ). It is not possible to use the keyboard to move the cursor or selection region to an arbitrary position when playing or recording. If you change low and high frequencies to kHz, then typing or incrementing values in the High Frequencies box has unpredictable results. You can't enter a new low frequency first if it is above the current high frequency - in that case, you must enter the new high frequency first. You could export the bindings, modify them in a text editor then import the modified list. VoiceOver and Orca do not read the key bindings at all. Keyboard Preferences: Window-Eyes doesn't read the key bindings when View by Tree is selected, and may not always read the bindings in other views. The names of the buttons are either not read by screen readers or the position of both options is incorrectly read as 1 of 1. Selection Toolbar: The End/Length buttons do not have a dotted rectangle to indicate when they have focus, and keyboard arrow keys no longer move between the buttons. shortcuts for Up, Down, Left, Right, Return and NUMPAD ENTER. When dragging or resizing an already undocked toolbar, the selected control similarly loses its focus border. After mouse down to drag a docked toolbar to a new docked or undocked position, the track focus is removed and the selected control loses its focus border even though that toolbar still has focus. Workaround: perform View > Toolbars > Reset Toolbars before enabling any disabled toolbars. Toolbars that show disabled at View > Toolbars and are then re-enabled will launch undocked if Audacity has already been restarted. 
There are some accessibility bugs in the parts of Audacity that are accessible (or behavior may vary according to the specific screen reader).It may be possible to make more of Audacity accessible in the longer term.

Many, but not all parts of the Audacity interface are accessible on Windows and Mac ( read the alert above about Mac) to those who can't use a mouse, and/or use a screen reader.Known Major Issues at Release Accessibility 1.27 Miscellaneous platform-specific issues.
