We ignore keystrokes like alt-left-arrow and alt-right-arrow,
so that the browser can do back/forward.
We may need to refine the handling of ctrl/alt/shift in the
future, but now we only support single-key operations.
This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
Explaining the problem a bit: When we narrow to a stream/private message
using `q+Enter`/`w+Enter` compose box opens which isn't desirable here.
The bug here was the propagation of event after getting handled in
`keydown_util.handle` to `hotkeys.process_enter_key`.
Fixes: #9679.
This introduces a generic class called list_cursor to handle the
main details of navigating the buddy list and wires it into
activity.js. It replaces some fairly complicated code that
was coupled to stream_list and used lots of jQuery.
The new code interacts with the buddy_list API instead of jQuery
directly. It also persists the key across redraws, so we don't
lose our place when a focus ping happens or we type more characters.
Note that we no longer cycle to the top when we hit the bottom, or
vice versa. Cycling can be kind of an anti-feature when you want to
just lay on the arrow keys until they hit the end.
The changes to stream_list.js here do not affect the left sidebar;
they only remove code that was used for the right sidebar.
This is a pretty thin abstraction to prevent having to put
magic numbers in code, doing the which/keyCode hack, and remembering
to all preventDefault.
Hopefully we'll expand it to handle things like shift/alt keys
for components that want their own keyboard handlers (vs. going
through hotkey.js).
