For years I've been using Slime's keyboard shortcut to bring up my browser on a local copy of the hyperspec using the standard Ctrl-c d h shortcut. Now its started launching a new email window in Thunderbird, my email client, instead.

I'm running Ubuntu 18.04, Emacs 25.2.2, and Slime 2.24.

Anyone run into this? Any idea how to fix it?

You need to identify what emacs package you loaded that overrides the C-c d h keybinding.
Note that slime-documentation-lookup is normally bound to C-c C-d h 
So C-c d h must have been put there by yourself in your ~/.emacs 
Try to do that at the end of your ~/.emacs, to get a chanc to override the key binding yourself.

Thanks for the reply.  I didn't spell that key combination right. I meant C-c C-d h. I haven't changed the default documentation key bindings. Nor have I modified .emacs (~/.emacs.d/init.el for my system) in ages.  There is no binding over-ride for C-c C-d h in it that I can see.

I suppose that means some package I've been using took over that key combination in an automatic package update. So presumably I could restore it by manually re-assigning it at the end of the file? Something like

(global-set-key (kbd "C-c C-d h" 'hyperspec)

which doesn't work.


Because the package in question probably overrides it locally.  Type C-h m in the buffer where you have the wrong binding to see what binding you have and where it comes from.
Also, C-h k C-c C-d h will tell you what command is bound. Find where this command is defined and what loads it.
