Go to the main Info buffer with
C-h i. Hit
d to make sure you are
at the top-level of the Info documentation, and go at the beginning of
the buffer with
Perform an incremental search for “lisp” with
RET to deactivate the search and the highlighting of search
C-r to search backwards.
C-s C-s to search for the last search string again.
M-e to edit the search string. Delete “lisp” in the minibuffer
prompt, type “mode” and
RET to reenter the search loop.
M-p. Your cursor will be back in the minibuffer prompt and you
M-n to cycle through previous search strings, and
to search the selected string again.
Go back to the beginning of the Info buffer with
C-s to start the search.
C-q C-j to search for the newline character.
C-q is used to insert
RET literally: if you don’t use
RET in the search prompt will exit the prompt.
C-g to abort the search.
C-s and search for
Notice that both “Mail” and “mail” will be matched: the search is not case sensitive.
C-u C-SPC to go back to your position before your search.
While in the search loop, hit
M-s c) to toggle case
sensitivity: you will notice that now only “mail” is highlighted.
While in the search loop, hit
M-s SPC to toggle “match spaces
loosely”: when matching spaces loosely, you can search for a string
like “mail client” (with three hard spaces) and still match the
“mail client” string.
Still in the search loop,
M-s w will perform word-based searches. For
example, word-based search for “mail” will not match “email”.
Now try searching for
maii instead of
edit the search string by deleting the last character.
C-s and search again for “mail”.
RET on the first occurrence and go one word backward with
C-s C-w to search for the word at point (it should be “mail”).
Try again with
C-s C-w C-w to search for several words at point.
C-s C-M-y to search for the character at point.
C-M-y C-M-y to add the next two characters to the search string.
C-M-w to remove the last character from the search string.
Exit the search with
Info buffers are read-only by default: hit
M-d on a word to copy it.
In normal buffers, you would use
C-M-SPC to mark the “sexp” under
cursor (here, the “sexp” is simply a word), then
M-w to copy it
(i.e. to “add it to the kill-ring).
C-s again, then
C-y to paste (i.e. “yank”) the text in the
C-s C-M-i. This will displays a new window with a list of
possible completions for the current search string.
C-s to search for “mail”.
M-s o to list lines where “mail” occurs.
M-s r) to switch to regular expression search.
Go to an org-mode buffer. Hit
M-TAB to cycle through visibility
status and stop when in the
OVERVIEW mode (everything is folded).
Search for hidden text: the matched string is automatically unfolded when the cursor moves to it.
Exit the search.
Still in this org-mode buffer, hit
M-TAB to fold the subtrees and hit
C-s M-s i to search for visible text only. Invisible text won’t be
In any buffer, hit
C-s C-h b to browse the search options.
Things I wish I knew sooner:

C-s M-rto toggle search by regular expressions
C-s M-s oto run

C-s C-M-ito complete the current search string
