To install this package, run in Emacs:
M-x package-install RET do-at-point RET
The command `do-at-point' is a generalised `find-file-at-point', both in the sense that it can understand more than just files, and do more than just open a file. Depending on the "thing" at point, different "actions" can be dispatched, e.g. opening a url using `browse-url' or occurring a symbol at point. The entry point of this package is `do-at-point'. Bind it to a convenient key: (global-set-key (kbd "C-'") #'do-at-point) Most of the behaviour is controlled via the user option `do-at-point-actions' and `do-at-point-user-actions'. A mode may use `do-at-point-local-actions' to add additional things and/or actions.
