- You don't have to be in the compilation buffer in order to use

-if the current buffer can be the target of @code{next-error}, it is
-used. Else, all the buffers Emacs manages are tried for

-By default, watch expressions only display in the speedbar when the

-radio button on the @samp{Speedbar->Displays} sub-menu using
-@kbd{Mouse-3}.
