use this to add descriptions to the default key bindings. A new -N flag
to list-keys shows key bindings with notes rather than the default
bind-key command used to create them. Change the default ? binding to
use this to show a readable summary of keys.
Also extend command-prompt to return the name of the key pressed and add
a default binding (/) to show the note for the next key pressed

there should be no change to existing behaviour) and are set and shown

This makes select-pane -P and -g unnecessary so no longer document them

parser using yacc(1). This is a major change but is clearer and simpler
and allows some edge cases to be made more consistent, as well as
tidying up how aliases are handled. It will also allow some further
improvements later.
Entirely the same parser is now used for parsing the configuration file
and for string commands. This means that constructs previously only
available in .tmux.conf, such as %if, can now be used in string commands
(for example, those given to if-shell - not commands invoked from the
shell, they are still parsed by the shell itself).
The only syntax change I am aware of is that #{} outside quotes or a
comment is now considered a format and not a comment, so #{ is now a
syntax error (notably, if it is at the start of a line).
This also adds two new sections to the man page documenting the syntax
and outlining how parsing and command execution works.
Thanks to everyone who sent me test configs (they still all parse
without errors - but this doesn't mean they still work as intended!).

changes to allow the status line to be entirely configured with a single
option.
Now that it is possible to configure their content, enable the existing
code that lets the status line be multiple lines in height. The status
option can now take a value of 2, 3, 4 or 5 (as well as the previous on
or off) to configure more than one line. The new status-format array
option configures the format of each line, the default just references
the existing status-* options, although some of the more obscure status
options may be eliminated in time.
Additions to the #[] syntax are: "align" to specify alignment (left,
centre, right), "list" for the window list and "range" to configure
ranges of text for the mouse bindings.
The "align" keyword can also be used to specify alignment of entries in
tree mode and the pane status lines.

some modern features.
Now the common code is in mode-tree.c, which provides an API used by the
three modes now separated into window-{buffer,client,tree}.c. Buffer
mode shows buffers, client mode clients and tree mode a tree of
sessions, windows and panes.
Each mode has a common set of key bindings plus a few that are specific
to the mode. Other changes are:
- each mode has a preview pane: for buffers this is the buffer content
(very useful), for others it is a preview of the pane;
- items may be sorted in different ways ('O' key);
- multiple items may be tagged and an operation applied to all of them
(for example, to delete multiple buffers at once);
- in tree mode a command may be run on the selected item (session,
window, pane) or on tagged items (key ':');
- displayed items may be filtered in tree mode by using a format (this
is used to implement find-window) (key 'f');
- the custom format (-F) for the display is no longer available;
- shortcut keys change from 0-9, a-z, A-Z which was always a bit weird
with keys used for other uses to 0-9, M-a to M-z.
Now that the code is simpler, other improvements will come later.
Primary key bindings for each mode are documented under the commands in
the man page (choose-buffer, choose-client, choose-tree).

reasonable amount (currently width * height * 8 bytes), discard all
output to the terminal and start trying to redraw periodically
instead. Continue with this until the amount of data we are trying to
write falls to a low level again.
This helps to prevent tmux sitting on a huge buffer of data when there
are processes with fast output running inside tmux but the outside
terminal is slow.
A new client_discarded format holds the amount of data that has been
discarded due to this mechanism.
The three variables (when to start this, when to stop, and how often to
redraw) are basically "works for me" at the moment, this is going in to
see how it goes and if it causes problems for anyone else.
falls back to an alternative if the tty name is not available. This is
clearer than overloading the client ttyname member and allows us to
remove the path stored in the tty struct, it should always be the same
as the client.
main issue is that if we have two panes, A with 1002 and B with 1003, we
need to set 1003 outside tmux in order to get all the mouse events, but
then we need to suppress the ones that pane A doesn't want. This is easy
in SGR mouse mode, because buttons == 3 is only used for movement events
(for other events the trailing m/M marks a release instead), but in
normal mouse mode we can't tell so easily. So for that, look at the
previous event instead - if it is drag+release as well, then the current
event is a movement event.

A selection made with the mouse will stay as it is after button 1 is
released. (It also works bound to a key.)

but there is also now a global command queue. Instead of command queues
being dispatched on demand from wherever the command happens to be
added, they are now all dispatched from the top level server
loop. Command queues may now also include callbacks as well as commands,
and items may be inserted after the current command as well as at the end.
This all makes command queues significantly more predictable and easier
to use, and avoids the complex multiple nested command queues used by
source-file, if-shell and friends.
A mass rename of struct cmdq to a better name (cmdq_item probably) is

confusing, particularly trying to automatically figure out what target
hooks should be using. So simplify it:
- drop before hooks entirely, they don't seem to be very useful;
- commands with special requirements now fire their own after hook (for
example, if they change session or window, or if they have -t and -s
and need to choose which one the hook uses as current target);
- commands with no special requirements can have the CMD_AFTERHOOK flag
added and they will use the -t state.
At the moment new-session, new-window, split-window fire their own hook,
and display-message uses the flag. The remaining commands still need to
be looked at.
support line editing and instead executes a command as soon as a
non-number key is pressed. Add a -N flag to command-prompt for the same
in copy mode. Reported by Theo Buehler.
The vi-copy and emacs-copy mode key tables are gone, and instead copy
mode commands are bound in one of two normal key tables ("copy-mode" or
"copy-mode-vi"). Keys are bound to "send-keys -X copy-mode-command". So:
bind -temacs-copy C-Up scroll-up
bind -temacs-copy -R5 WheelUpPane scroll-up
Becomes:
bind -Tcopy-mode C-Up send -X scroll-up
bind -Tcopy-mode WheelUpPane send -N5 -X scroll-up
This allows the full command parser and command set to be used - for
example, we can use the normal command prompt for searching, jumping,
and so on instead of a custom one:
bind -Tcopy-mode C-r command-prompt -p'search up' "send -X search-backward '%%'"
command-prompt also gets a -1 option to only require on key press, which
is needed for jumping.
The plan is to get rid of mode keys entirely, so more to come eventually.
