STARTED(s!) WAITING(w@) APPT(a!) | DONE(d!) CANCELLED(c!) DEFERRED(f!) * 2018 ** 2018-02 March *** 2018-02-12 Monday **** Demonstrating Emacs/Orgmode shortcuts These informations were gathered and first demonstrated in my [[https://github.com/alegrand/RR_webinars/blob/master/1_replicable_article_laboratory_notebook/index.org][First webinar on reproducible research: litterate programming]]. ***** Emacs shortcuts Here are a few convenient emacs shortcuts for those that have never used emacs. In all of the emacs shortcuts, =C=Ctrl=, =M=Alt/Esc or Cmd with MacOs= and =S=Shift=. Note that you may want to use two hours to follow the emacs tutorial (=C-h t=). In the configuration file CUA keys have been activated and allow you to use classical copy/paste (=C-c/C-v=) shortcuts. This can be changed from the Options menu. - =C-x C-c= exit - =C-x C-s= save buffer - =C-g= panic mode ;) type this whenever you want to exit an awful series of shortcuts - =C-Space= start selection marker although selection with shift and arrows should work as well - =C-l= reposition the screen - =C-_= (or =C-z= if CUA keys have been activated) - =C-s= search - =M-%= replace - =C-x C-h= get the list of emacs shortcuts - =C-c C-h= get the list of emacs shortcuts considering the mode you are currently using (e.g., C, Lisp, org, ...) - With the "/reproducible research/" emacs configuration, ~C-x g~ allows you to invoke [[https://magit.vc/][Magit]] (provided you installed it beforehand!) which is a nice git interface for Emacs. There are a bunch of cheatsheets also available out there (e.g., [[http://www.shortcutworld.com/en/linux/Emacs_23.2.1.html][this one for emacs]] and [[http://orgmode.org/orgcard.txt][this one for org-mode]] or this [[http://sachachua.com/blog/wp-content/uploads/2013/05/How-to-Learn-Emacs-v2-Large.png][graphical one]]). ***** Org-mode Many emacs shortcuts start by =C-x=. Org-mode's shortcuts generaly start with =C-c=. - =Tab= fold/unfold - =C-c c= capture (finish capturing with =C-c C-c=, this is explained on the top of the buffer that just opened) - =C-c C-c= do something useful here (tag, execute, ...) - =C-c C-o= open link - =C-c C-t= switch todo - =C-c C-e= export - =M-Enter= new item/section - =C-c a= agenda (try the =L= option) - =C-c C-a= attach files - =C-c C-d= set a deadl1ine (use =S-arrows= to navigate in the dates) - =A-arrows= move subtree (add shift for the whole subtree) ***** Org-mode Babel (for literate programming) - =
