Regular Expressions

Match a new line in the minibuffer

match a newline, \n, with C-j.
In the minibuffer, you have to type:

C-q C-j

The C-q quotes the following sequence C-j.

Match Parentheses

with ( or ). In emacs, it is reversed, use ( to match paren, and \( and \) to open and close a group.

backslashes

  • use \\ to quote a character in elisp code
  • use a single backslash to quote in the minibuffer
  • Tramp

    with Tramp you use the same "write-file" command with keybinding C-x C-w and then give a remote ssh path as the file path
