TiddlersBarPlugin: keyboard shortcuts

[FND]

Pascal,

Would it be possible to introduce keyboard shortcuts for your
TiddlersBarPlugin to switch between tabs?
Since both ALT+TAB and STRG+TAB are taken, how about using the left and
right arrow keys with the browser access key (usually ALT or SHIFT+ALT)?

(Surprisingly, I couldn't find any discussion of this in the group
archives - am I missing anything?)

Good idea,

I will look on that. Does somebody knows if there are some embedded
methods in TW to handle keyevent ? Or should I use addeventlistener at
document level ?

I only know that there's onTiddlerKeyPress() - but I'm no really
familiar with it.

Glad you're open to the idea though!

This function is NOT a general hook to process keystrokes from any
tiddler.

onTiddlerKeyPress() is intended to add handling for special keys TAB,
ENTER/CTRL-ENTER, ESC, etc. that propagate ("bubble up") to the
tiddler DOM element from text input fields contained within that
tiddler's content, typically defined by the [[EditTemplate]], and
shown only when the tiddler is being edited.

Also, be very careful when writing code that hooks onto the document-
level keystroke event handler. Event handling protocols for different
browsers use different models. For example, IE doesn't like
"onkeypress" handlers.

In addition, "access keys" on different platforms use different
modifier-key combinations (e.g. PC uses ALT-SHIFT-letter, Mac uses
"command"-letter).

Lastly, I think that Bradley Meck wrote a generalized "key binding"
plugin that works cross-platform, and let's you bind alomst any
keystroke (not just "access keys") to almost any function. Sorry, I
don't have the URL at the moment.

Hi Eric,

could it be you talk about CaptureKeysMacro? It would be here:

Yup! That's the one!

Thanks for all these precious informations ! It seems that
CaptureKeysMacro does the main job. I will try it on tiddlersBar
during the next days and give you some feedback.

Actually, CaptureKeysMacro is a huge plugin (~10 kB), and most of its
code is probably not required for this particular purpose.
So, if possible, please only include the crucial portions in
TiddlersBarPlugin - nobody likes bloated plugins... ;)

Pascal,

I don't forsee any real reason why you would need the CaptureKeysMacro. TiddlyWiki has an addEvent method that you should be able to use, to add events to the document in a cross-browser friendly manner.

Hope that helps,

Saq

unlike regular keyboard events, the browser's implementation of access
key handling can differ between platforms, and access key events may
not always passed to the normal keystroke event handlers (i.e.,
onkeypress, onkeydown, onkeyup).

For example, CTRL-TAB is used by FireFox to switch between tabs. The
browser processes this keystroke AFTER onkeypress, but BEFORE
onkeydown/onkeyup. Thus, to use this keystroke for your own purposes,
you have to handle 'onkeypress' events... BUT... IE doesn't seem to
like 'onkeypress' handling...

also, when you CAN process keystrokes, you may have to account for
cross-platform differences in 'keycode' mappings, as well as I18N
issues such as handling UTF-8 conversion of character values.

In any event (pun intended :-), these are just two examples of how the
keystroke event processing models for different browsers can make this
a non-trivial problem... which is what lead Bradley to write
CaptureKeysPlugin in the first place.

Indeed, key events seems to be a very specific matter (cross browser
and cross platform issues !). So I think, the reasonable way to do the
job is to use CaptureKeysMacro. One other reason is that, if someone
uses key shortcuts, he might uses them for many purposes (vs just tab
switching).

Hi all,

The update I put online (version 1.2.5) has two parameters for
switching to the next or previous tab. I did it the simplest way,
using the TW embedded solution (ie createTiddlyButton function
accesskey parameter). So, it works as the standard "alt-shift-n" key
shortcut (that creates a new tiddler).

Pascal

Hi all,

I'm new to TiddlyWiki and this Group as well. It's a bit late to ask questions here as this thread is about 4 years old.
I installed your plugin, but I don't know how to configure the plugin in order to use the shortcut feature to switch between tabs.
I hope that someone could give me a hint.

Kind regards,
Albert
