Another way would be to use Tracks > Add New > Time Track. SHIFT + M
to open the menu, down arrow four times to "Set Range" and ENTER. Choose
the same figure in the "Lower speed limit" and "Upper speed limit" boxes
for constant speed playback.
In theory this would then let you remove the Time Track at any stage of
your project to play back at normal speed. But if you apply the Change
Speed effect, you must undo it before making other edits, or lose your
subsequent edits if you undo it later. However the Tracks > Remove Tracks
menu item only works with Audio and Label Tracks, which should be fixed.
In the "Play-at-speed" Toolbar, sighted users can double-click the slider
to get a text box to enter the exact figure, so it works like the gain and
pan sliders on the Track Panel. These sliders have a shortcut to access
the text box, so that would be the solution with the play-at-speed
slider. However given this is experimental I'd tend to call it a "feature
request" rather than a bug.
