Question: How to see/scroll throgh aw-dispatch-alist?

[ardpp]

When I call ace-window followed by ?, then aw-dispatch-alist is shown in the minibuffer which is too long in my case and is cut above. During an ivy completion of, for instance, counsel-find-file I can always press C-o to call hydra-ivy/body and grow/shrink the minibuffer.

Is there a possibility to have something similar for aw-dispatch-alist? At the moment any key not contained in this list or in aw-keys gives an error like "No such candidate ..."

Yes, I've noticed that sometimes using message will truncate the displayed lines. I'm not aware of a generic solution to this. Any info welcome.

Would be nice to implement something like ivy-dispatching-done-hydra for ace-window. PRs welcome.

I've got a hack to put this message into two columns, as the topic came up on reddit and I'd noticed it myself. It's naive in that it doesn't check the available display space, but the same is true for the current approach. If you'd like I could put this in a PR?

Hi, my workaround for this problem was to increase the value of max-mini-window-height, in my case it was enough: (setq max-mini-window-height 0.35)
