+*** Organisation #5: Emacs refresher
+**** Lecture content
+***** Objective: get confident with emacs commands
+***** Find out and document how to do the following steps
+
+Resources:
+
+C-h b
+A searchable list of commands and shortcuts, very helpful
+
+https://www.gnu.org/software/emacs/manual/html_node/emacs/
+https://www.emacswiki.org/emacs/
+https://www.gnu.org/software/emacs/refcards/pdf/refcard.pdf
+
+****** Search for something forward: C-s
+
+I've been using it, it's great!
+
+****** How to continue searching
+
+C-s multiple times.
+
+****** Search for something backward
+
+C-r
+
+****** Search for regular expressions instead of string (forward, backward)
+
+urxvt scrollback-search is already bound for : C-M-s
+there is no easy way to disable it atm
+note: maybe i'll try the suckless terminal or xterm
+
+
+C-M-r is working
+note: need to learn regex
+
+****** Go to the beginning of the line
+
+C-a
+
+****** Go to the end of the line
+
+C-e
+
+****** Delete a word in front (to the right of the cursor)
+
+C-del
+
+
+****** Delete a word in back (to the left of the cursor)
+
+M-backspace
+
+****** List all "occurences" of a word in a file
+
+
+M-x grep or grep-find - Return
+
+enter string and/or specify a file (default directory is set to the currently edited file) - Return
+
+The result will show up in a new windows. C-x-o to switch windows
+
+
+******* You can copy above instructions into an emacs buffer
+
+******* And test it by showing all occurences of the word "Search"
+
+
+
+
+****** Search (GREP) for a word in all files in a directory RECURSIVELY
+
+M-x grep(-find) - Return
+add "-r" to the executed grep command
+
+****** Save the CURRENT buffer
+
+C-x C-s
+
+****** Save ALL open files
+
+C-x s
+
+****** Split the window/buffer vertically
+
+C-x 2
+
+****** Split the window/buffer horizontally
+
+C-x 3
+
+****** Switch between the different windows
+
+C-x o
+
+****** Close all buffers besides the active one
+******* Don't kill it!
+
+C-x 1
+
+****** Close only the active buffer
+
+There is no "Close buffer" per se (spent 10 minutes finding it)
+
+The way is to Close the Window: C-x 0
+
+List the buffers by: C-x C-b (you can switch to the buffers from this buffer (ret))
+
+
+******* Don't kill it
+
+C-x k 
+to kill it
+
+****** Kill the active buffer
+
+C-x k
+
+****** Describe/Explain the difference between closing and killing
+
+It's like tmux:
+
+"Closing" just stops the rendering, and it will continue to run in the background.
+Killing stops the process and frees up the memory.
+
+****** Switch between buffers that are not shown
+
+C-x b (tab to list buffers)
+
+
+******* Document two very similar, but slightly different ways
+
+Switch buffers quickly:
+C-x <left>
+C-x <right>
+
+ido mode should speed up buffer switching (haven't tried)
+
+
+***** Outcome
+****** Document all above commands in your learning org sheet
+****** Share your documentation at the end of the session (not before)
+
