Files/windows navigation

Emacs

Intro.

In Part 1 of Emacs series I presented the movement (or navigation within a single buffer/window), in this part I am going to demo the navigation between multiple windows/files/buffers.

In mode-line (status bar) you can see the keys that are being pressed and the functions that are executed.

A bit if Emacs terminology:

  1. Frame - top level graphical object associated with underlying Emacs process

  2. Window - a frame can be split in multiple windows

  3. File - a file on disk

  4. Buffer - a file that is opened in a window

1 Frames navigation

Since a frame is just a GUI app it will not be very interesting to demo new/close or resize actions so I will skip it.

1.1 new/close frame

  • new frame: SPC-q-m

  • close frame: SPC-q-d

  • quit emacs (close all frames): SPC-q-q

  • restart emacs: SPC-q-r

1.2 resize frame

  • toggle fullscreen: SPC-q-f

2 Files navigation

Finding files is simple, yet very powerful and with 3 key stokes I can reach any file on my computer in no time.

2.1 find file

  • in current project: SPC-f-p

  • in all known projects: SPC-f-P

  • globally (on disk): SPC-f-G

2.2 find directory

  • parent of current file: SPC f j

  • within project: SPC f d

2.3 find extension

  • file with different extension: SPC f e

3 Windows navigation

All window related commands are bundled under "SPC w" keymap as follows.

3.1 split window (aka new)

  • horizontally: SPC-w-|

  • vertically: SPC-w- -

3.2 go to window

  • left, right: SPC-w-h, SPC-w-l

  • bottom, top: SPC-w-j, SPC-w-k

  • selection: SPC-w-w-1, SPC-w-w-5

  • swap: SPC-w-s-4

3.3 delete window

  • selection: SPC-w-D-3

  • this window: SPC-w-d

  • other windows: SPC-w-x

3.4 resize window

  • golden ratio: SPC w g

4 Buffers navigation

A buffer is just a file that is opened in a window.

4.1 switch to buffer

  • project buffer: SPC-b-p

  • select any buffer: SPC-b-b

  • special buffers like dashboard: SPC-b-g-d

/img/emacs/switch-buffer.gif

4.2 new/save/close buffer

  • new: SPC-f-p (automatically when a file is opened)

  • close: SPC-b-d

  • save: SPC-b-s

The curious minds please check the config files for vanilla emacs.
