Completions in a header

In header, completions each field are assigned to `TAB' as follows:

• Field completion
• Address completion and expansion (To:, Cc:, etc)
• Folder completion (Fcc:)

<Field completion>

If the cursor is on the beginning of a line and the previous line does not end with ",", you can complete field defined in the `mew-fields' variable with `TAB'.

To: kazu@mew.org
R`TAB'

At the point above, if you type `TAB', you get:

To: kazu@mew.org
Reply-To: 

<Address completion and expansion>

You can define an easy-to-remember short name for a long or hard-to-remember address with Mew's Addrbook feature. For example, consider the following configuration:

pooh:           winnie-the-pooh@100acre.woodwest.uk

This means to replace the string "pooh" with "winnie-the-pooh@100acre.woodwest.uk". Note that short names should usually be configured in "~/.im/Addrbook". For more information about Addrbook, please refer to See section Address Book.

In a header in Draft mode and on the field supposed to write addresses and one or more characters precede, you can complete an short name for address with `TAB'.

Let's look at the following example.

To: piglet@beech.tree.uk, 
        po`TAB'

If you input `TAB' up above, "pooh" is completed (unless other candidates exist).

To: piglet@beech.tree.uk, 
        pooh`TAB'

One more type of `TAB' expands it to "winnie-the-pooh@100acre.woodwest.uk".

To: piglet@beech.tree.uk, 
        winnie-the-pooh@100acre.woodwest.uk

If you type `TAB' at improper point for address completion, `TAB' is inserted. Consider the following example:

To: pooh,`TAB'

In this case, `TAB' is just inserted.

A string ended with "@" is explicitly expanded. Consider the following case where similar short names are defined.

pooh:           winnie-the-pooh@100acre.woodwest.uk
pooh-pooh:      pooh-pooh@somewhere.jp

To expand "pooh" to "winnie-the-pooh@100acre.woodwest.uk", take this way.

To: pooh@`TAB'

<Folder completion>

At a point, such as Fcc:, supposed to complete a folder, you can complete a folder with `TAB'. Let's look at an example.

Fcc: `TAB'

Here, "+" is completed.

Fcc: +`TAB'

One more type of `TAB' shows candidates. Please input appropriate characters then type `TAB'.

Fcc: +B`TAB'

If a candidate can be solely decided, you get a completion.

Fcc: +Backup

<Hints of customization>

You can define which field allows address and folder completion in `mew-field-completion-switch'. The following declaration is used by default.

(defvar mew-field-completion-switch
  '(("To:"        . mew-complete-address)
    ("Cc:"        . mew-complete-address)
    ("Dcc:"       . mew-complete-address)
    ("Bcc:"       . mew-complete-address)
    ("Reply-To:"  . mew-complete-address)
    ("Fcc:"       . mew-complete-folder)
    ("Resent-To:" . mew-complete-address)
    ("Resent-Cc:" . mew-complete-address)
    ("Config:"    . mew-complete-config)))

Please refer to See section Config to know completion for Config:.
