1c2dd4c9f1 bindings: properly check for exKey keystrokes
When checking for an exKey, aerc inspects the key and the rune of the
event vs the exkey binding. Runes should only be inspected if the key is
a tcell.KeyRune. Some Ctrl-[:alpha:] keys report a rune in tcell, but
aerc does not have these bound to the keystroke definition. Only <C-x>
has a rune bound, and is one of the very few <C-> keys that can actually
be bound to exKey

Only compare the Rune field if the key is of type KeyRune. Otherwise,
compare the Key. Also compare any modifiers with the keystroke/key
event. These changes allow for any control or alt key combination to be
bound to the exkey.

Update documentaiton to reflect that the default keybind is ':', and not
<semicolon>

055c6dc660 exline: don't draw completions for keybinds
The exline widget works by matching actual keystrokes to a map of
keybinds, and if a match is found sending simulated keystrokes through
aerc. This has the effect of aerc thinking we are actually typing in the
expanded command, and aerc attempts to draw the completions. This
results in even basic navigation having two screen draws:

For example, pressing 'j' to select the next message (:next), draws once
for the initial key event and state change, and again after the
completion debounce timer.

Disable tab completion while aerc is simulating keystrokes. If the
exline still has focus after simulating keystrokes, restore tab
completion.

index in that array. The these two fields are sometimes modified in

4d3156ddf1 aerc: fix panic when backend is unknown
A panic occurs when an unknown backend is used. This regression was
introduced by commit a34be9eb36 ("status: use contextual ui styleset

backend was displayed. The contextual ui requires an account-specific ui
config but when the backend throws an error in the constructor of the
account view, the call to aerc.SelectedAccountUiConfig() panics:

panic: runtime error: index out of range [0] with length 0 [recovered]

74366d895d viewer: add key passthrough mode
When trying to search in less, keys bound to viewer functions can't be
used as part of the search query, which makes the search useless.

Add a view::passthrough binding mode and a :toggle-key-passthrough

viewer is bound to enabling key passthrough and automatically inserting
'/', to easily enter "less" search mode. When in the passthrough mode,
all bindings are ignored by default. The default binds.conf only defines
a single keybinding in that mode: <Esc> to get back out. $ex is bound to
<C-x> to allow typing colons.

175d0efeb2 binds: add account specific bindings
When using aerc for multiple accounts often bindings might differ
slightly between accounts. For example:

* Account A archives to one directory (:archive)
* Account B archives to monthly directories (:archive month)

Add account specific bindings to allow the user to add a "context" to a
binding group using a context specifier and a regular expression.

Currently the only context specifier is 'account'.

The regular expression is validated against the accounts loaded from
accounts.conf and the configuration fails to load if there are no
matches.

Contextual bindings are merged with global bindings, with contextual
bindings taking precedence, when that context is active.

Bindings are be configured using a generic pattern of
'view:context=regexp'. E.g.:

    # Globally Applicable Archiving
    [messages]
    A = :read<Enter>:archive<Enter>

    # Monthly Archiving for 'Mailbox' Account
    [messages:account=Mailbox$]
    A = :read<Enter>:archive month<Enter>

In the above example all accounts matching the regular expression will
archive in the monthly format - all others will use the global binding.
