[mythtv-users] Version 30.0 and toggle bookmarks confusion

[Tom Dexter]

I haven't updated to 30.0 as yet but was going to soon. I'm glad I
decided to look at the database schema update code because there where
two things in there that pointed me towards changes that seemed a bit
significant...especially for things not mentioned in the release notes
at all. I'll get into the second in another email.

I noticed the removal of the settings table entry for
"AltClearSavedPosition" was being removed. That's lead me to massively
confusing and conflicting threads regarding new TOGGLEBOOKMARK and
SETBOOKMARK bindings and the fact that, apparently, the existing
SELECT action is no longer used for that(??).

My remote control (using ir-keytable) is currently using the space key
for this. Currently I have these entries in keybindings:

+---------+------------+----------------------+--------------------+-----------+
| context | action     | description          | keylist            | hostname  |
+---------+------------+----------------------+--------------------+-----------+
| Global  | SELECT     | Select               | Return,Enter,Space | mythback  |
| Global  | SELECT     | Select               | Return,Enter,Space | mythfront |
| Browser | FOLLOWLINK | Follow selected link | Return,Space,Enter | mythback  |
| Browser | FOLLOWLINK | Follow selected link | Return,Space,Enter | mythfront |
+---------+------------+----------------------+--------------------+-----------+

The browser ones are irrelevant in my case...no clue what added those.

On one hand I'm reading that existing frontends should work as they
always did and that this only affects new frontends. Yet I'm also
reading that there's no default for any of this, and it's clear
there's no schema update adding anything to keybindings. None of this
is adding up for me.

Given that I want to maintain the existing bookmark toggle behavior
(ideally for Return,Space,Enter of at least Space), can anyone clarify
these:

1. What actually will be the default behavior of Return,Enter,Space
after the update on my existing frontend?

2. If I have to do in fact need to add TOGGLEBOOKMARK key bindings,
will they conflict with any of the above, or do they only apply to the
"TV Playback" context?

3. Related to #2 do these bindings also maintain the bookmark toggle
in video / DVD playback.

Thanks in advance for any clarification.
