The function modals.is_active() can see if modals are open
without having to look at the DOM. This should make it snappier
to type in the compose box. Even if the speedup is pretty minor,
not having to worry about jQuery slowness should make it easier
to diagnose future compose box issues.
The new function gets used in other places, too, where performance
isn't so much an issue.
This focuses the body content of the informational overlay after
going to it from "?" so that you can use up and down arrows to then
scroll the content easily.
Fixes: #4480.
This moves respond_to_mention() and reply_with_mention() to
compose_actions.js. These methods are basically thin layers
on top of compose_actions.start().
We've had this kind of hacky setting called message_view_only for
a long time in the hotkeys code, and it originally helped optimize
the code a bit. It wasn't well maintained, and people started
adding non-message-view behavior to the arrow keys without flipping
that flag to false. This change finally flips the flag to false,
which simplifies some of our logic.
We now explicitly return true from process_hotkey() when we
handle up/down/backspace for the drafts modal. Also, we no longer
call preventDefault() from drafts.draft_handle_events(), since the
caller does that, and we no longer return `true`, since we were
never inspecting the return value anyway.
The up/down arrows now navigate the left pane of the settings menu.
The code here was originally implemented as part of our settings
redesign, but the code was added in a place that became unreachable
after we fixed a bug with home_tab_obscured(). This commit
resurrects the code and places the guts of it in settings.js. It
is possible that we want to clean this code up eventually to deal
better with hidden blocks.
The code here used to live in hotkey.js. Its complicated calling
protocol made it difficult to unit test. We are also trying to
slim down hotkey.js.
Our arrow navigation for things like `#stream_filters` has always
been kind of awkward, since it's difficult to get the focus to
their list items. This commit does nothing to fix that yet.
* 'd' in message view opens drafts.
This also adds hotkeys within the drafts UI:
* Up/down arrow keys navigate the drafts.
* Pressing enter edits the selected draft.
* Pressing backspace deletes the selected draft.
Some variable names tweaked by tabbott.
This adds an image feed that you can scroll through with hotkeys
in the lightbox.
The left and right arrow keys along with the left and right arrows
will go to the prev/next image, and clicking on an image will also
take a user to that image.
We simplify hotkey mappings by using different hashes for
keydown and keypress events. There are browser bugs (iOS, for
example) where keypress events have the wrong keyCode values.
This led us, under iOS, to interpret "!" as "page up."
This fix also helps us disinguish escape from shift-escape.
Brock Whittaker helped on figuring out the keypress/keydown
issues that are addressed in this commit.
Fixes#4019
The initial version of the tests cover most normal keys, but they
do not cover special keys like enter/tab/escape or arrow keys
or home/end/page-down/page-up yet.
