Most important Emacs commands

Keep in mind that this page was created from a simple markdown-to-html ruby program called rdiscount

• Switch cursor to another window - C-x o
• Switch buffers - C-x left, C-x right, list them all with C-x C-b, kill one with C-x k
• Delete all other windows - C-x 1
• Delete this window - C-x 0
• Split window above and below - C-x 2
• Split window side by side - C-x 3

  This can be done a bunch of times to create a bunch of small skinny windows

• Read a file into Emacs - C-x C-f
  • This can create a new file as well
  • Type tab to see potential files to open
• Save a file to disk - C-x C-s
  • Save all files! - C-x s
• Go to line M-g g
• Go to char M-g c
  • Back to indentation M-m

Moving around

We know how to move around character by character C-f and C-b - Words - M-b and M-f - Ctrl-left and Ctrl-right also work - Lines - C-a - beginning of line, C-e - end of line - Sentences - M-a and M-e - Paragraphs - M-{, M-} - In windows terms it's Alt-Shift-[ or Alt-Shift-]

• Buffer beginning and end - M-<, M->

Practical uses to learn

How to switch windows, cut/kill a line and yank to other window

C-o, then C-k to kill to end of line. Then C-o, M-> to buffer end, then C-y to yank it back.

Let's try it.

Starting in Windows PowerShell 5.0, results of the Get-Command cmdlet display a Version column by default. A new Version property has been added to the CommandInfo class.

`Get-Command` gets its data directly from the command code, unlike `Get-Help`, which gets its information from help topics.

It worked!

How to search for a word or regex

• C-s search forward, C-r search backward.
• C-M-s and C-M-r for regex search (back and forth respectively)

  will beep when search gets to end of buffer.

How to search in other file

May need grep or some other tool - open (find) a file into another window - C-x 4 f - shows dialog on bottom of screen - "" in read-only mode - C-x 4 r

Case-sensitive

When opening a file in a separate window, it is case sensitive. If you're unsure of whether the file is capitalized or not, you can use tab to show the directory contents. I believe there might be a way to turn case-sensitive off

How to navigate thru text with ease

Remember M-f(b) for words and M-a(e) for sentences. Page down using C-v and M-v - (Sometimes C-v is set to paste, check terminal for settings.) abbrs work, and most editors can do syntax highlighting for both the .md syntax and the html syntax. So you can use code or code

How to take .md file and convert to .html

There are a few cli tools that allow you to do this. For this demo I'm going to use rdiscount
