The floating walkthrough panel that opens from the '?' button is now fully keyboard-operable — you can tab to either resize handle and grow or shrink the panel with the arrow keys instead of having to use a mouse. Two small accessibility improvements to the guide viewer's desktop resize handles: Tab to the resize handle, then arrow-key to resize — Both edges of the guide panel are now proper focusable buttons. Tab gets you there, a visible focus ring tells you which edge is active, and Left/Right arrows move that edge by 20 pixels at a time (Up/Down by 50). The width is clamped to the same range as the mouse drag and your last size is remembered between sessions, just like before. Arrow keys stop flipping the slide while you're resizing — Previously, the global keyboard shortcut that moves between guide slides could fire at the same time as a resize, so pressing Left to nudge the edge also flipped to the previous slide. With a resize handle focused, the slide-navigation shortcut now stays out of the way until you tab off.
