A function in the hook should first test if it would like to

taken to make the search successful, another function should be
|

added to the companion hook `org-execute-file-search-functions',

which see.

handle this search, for example by checking the `major-mode' or

numeric or double prefix to guide the search function.

Completion can be used to insert any of the link protocol prefixes in use.
|

|

The history can be used to select a link previously stored with
|
||
`org-store-link'. When the empty string is entered (i.e. if you just
|
||
press `RET' at the prompt), the link defaults to the most recently
|
||
stored link. As `SPC' triggers completion in the minibuffer, you need to
|
||
use `M-SPC' or `C-q SPC' to force the insertion of a space character.
|
||
|
||
You will also be prompted for a description, and if one is given, it will
|
||
be displayed in the buffer instead of the link.
|
||
|
||
If there is already a link at point, this command will allow you to edit
|
||
link and description parts.
|
||
|
||
With a `\\[universal-argument]' prefix, prompts for a file to link to. The \
|
||
file name can be
|
||
selected using completion. The path to the file will be relative to the
|
||
current directory if the file is in the current directory or a subdirectory.
|
||
Otherwise, the link will be the absolute path as completed in the minibuffer
|
||
\(i.e. normally ~/path/to/file). You can configure this behavior using the
|
||
option `org-link-file-path-type'.
|
||
|
||
With a `\\[universal-argument] \\[universal-argument]' prefix, enforce an \
|
||
absolute path even if the file is in
|
||
the current directory or below.
|

A `\\[universal-argument] \\[universal-argument] \\[universal-argument]' \

prefix negates `org-link-keep-stored-after-insertion'.

the link location instead of reading one interactively.

If the DESCRIPTION parameter is non-nil, this value will be used as the
|
||
default description. Otherwise, if `org-link-make-description-function'
