|
||||
***** Find out and document how to do the following steps
|
||||
|
||||
Resources:
|
||||
|
||||

|
||||
A searchable list of commands and shortcuts, very helpful

****** 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)
