OK, this is *MUCH* later, but I still had this marked unread in ordered
to deal with later, and I'm finally getting the appropriately rounded
tuit. =:^)
There are two executable scripts and one kmap file, placed in a "system"
location, and as many user menu files as desired. One menu file is
invoked first, but invocation is nestable, so it's possible for the first
one to invoke the scripts again, thus invoking an additional layer of
menus.
Here, I have two menu layers, a primary that selects the category (net,
config, games, etc), and a second, category menu, that launches the
desired action. It's thus three keys to launch anything I have
configured an action for, the kde-launcher key (to launch the scripts
with the primary menu), the category selector key (select the category
and launch that menu), and the action selector key (launch the app/action
configured for that key). (Originally, I had a single layer menu, much
larger, thus requiring only two keys. But that got unwieldy, so I added
a layer of indirection and a key to the sequence, breaking it into pieces
arrange by category.)
I'll post the files separately as replies. This is the instructions for
setting them up and using them.
First, create a separate konsole profile called "hkm" (without the
quotes, hkm being short for hotkey menu). This allows you to setup
different behavior for it than for your normal konsole. Here, my hkm
konsole profile has a MUCH smaller scrollback menu of only a hundred
lines, for instance, and I have the scrollbar set hidden, while it's
shown on my normal konsole profile. If you like you can also set a
distinctive font and background.
(You could skip the separate konsole profile or name it something else,
but if you do, you have to change the launcher script accordingly, since
it invokes the menu script with the "--profile hkm" option.)
Second, create a new window rule for the menu. If you don't already have
a window rule for your normal konsole windows, you'll probably want to
create one for them as well, setting anything you want to behave
differently than the konsole menu windows.
(The following description is for kde 4.9, other versions might be
slightly different. I'm describing the English terms, I'm not sure how
much of this might be localized. Window rules are found in kde settings,
workspace appearance and behavior, window behavior, window rules.)
On the window matching tab, set window class to "exact match" "konsole
konsole", and check "match whole window class". Set window role to
"substring match", "mainwindow#". Set window types to "normal window".
Set window title to "substring match" "Hotkey Menu". The window title
bit is extremely important, since otherwise this rule will likely match
ALL konsole windows. I actually had quite some trouble getting the rule
to apply ONLY to my menu windows, not all konsole windows, as I wanted
different window behavior. So if you change or localize this, as with
the konsole profile bit above, be SURE to change the launcher script
accordingly, or you won't get a match!
On the size and position tab, this is what I found works best for me:
Size checked, apply initially, 740,610. (Change the size as needed for
best menu display. If you change your fonts, this will need to change as
well. Again, this is different behavior than my normal konsole windows,
which have their own window rules. Since konsole will try to use the
same size as the last time and I wanted a different size for my menu
konsoles, I had to set it specifically. Maximized horizontally and
maximized vertically, checked, apply initially, no. (The rule for my
normal konsole windows maximizes vertically. Different behavior here, so
I have to set the rule.) Initial placement, checked, force, centered.
(You can experiment here, but I found my default "smart" window placement
policy did NOT work well for the menu, mostly because whatever it
launched then ended up in the wrong spot. Under mouse might be another
good choice.) Minimum size, checked, force, 640,480. (Again, this
differs from the setting I use for my normal konsole windows.)
On the appearance and fixes tab, focus stealing prevention, checked,
force, none. You'll be invoking with a hotkey and you always want it to
appear and activate, so no focus stealing prevention. (Without this, the
menu would sometimes appear unfocused, under whatever I was working on.
Confusing!)
That's the window-rules setup for the menu. OK and apply.
Third, still in kde settings, setup the key you want to invoke the menu.
Common appearance and behavior, shortcuts and gestures, custom shortcuts.
If you haven't setup any of your own shortcuts here before, I suggest you
create a new group. That's found under the edit button. Choose a name
for your customized settings. Here, I used my initials (JED).
Select that group and edit, new, global shortcut, command/url. Set the
title. Here, I called it Hotkey-menu.
On the trigger tab, choose a launcher key. Here, on my main system I
have a fancy internet/media keyboard with a whole bunch of "extra" keys,
so I use one of them, HomePage. On my netbook, I decided to use winkey-
space (winkey aka superkey aka hyperkey, depending on who you ask or
where you read about it) as the menu launcher.
On the action tab, set the command to "hkl" (hotkey launcher). That's
the name of the launcher script. Of course you can rename it as
desired. The command here just has to match the name of the launcher
script.
Hit apply, and you should be done setting up kde for use with the menu.
Now you just need the files. =:^)
The first script, hkl (hotkey launcher), is real short, just the shebang
and a single command (split here into two lines), so I'll include it
here. Modify the shebang and command as desired, but be sure to take
note above if you change the --title or --profile options, and of course
if you change the name of the second script from hkm, change the -e
invocation of it here, as well.
-------------- begin hkl -----------------
#!/bin/bash
exec konsole --nofork --title "Hotkey Menu" --profile hkm \
--hide-tabbar --hide-menubar -e hkm "$@"
-------------- end hkl --------------------
Save that file somewhere in your path, and set it executable. I put it
in the system's local bin dir, /usr/local/bin/, here.
The second script file, hkm (hotkey menu) is the hairy guts of the
thing. I place it in /usr/local/bin/ as well, of course set executable.
This script is well commented.
There's a number of default settings near the top of the script, which
you can change as desired. These include the location of the menu files
(in the hotkey.lst subdir under $XDG_CONFIG_HOME if it's set, with
~/.config/ the default for XDG_CONFIG_HOME if it's not set), and the
location of the keymap file (normally /usr/local/etc/hotkeylookup.lst,
see below).
There's three additional settings with a global value set here, that can
be overridden in the individual menu files if desired. These include a
30-second query-timeout after which the default key is invoked, a post-
launch timeout of 3 seconds, useful to see any errors spit out if
something doesn't launch, but you may wish to shorten this, and a global
default-key, normally escape (to cancel the menu), invoked if no key is
hit by the query-timeout. (See the in-script comments for per-menu-file
override instructions.)
There's also a keymap file, hotkeylookup.lst, used to translate control-
modified keys, thus giving you three hotkeys to choose from for most
letters, unmodified, shifted, and controlled. If you're happy with only
unmodified and shifted (no controlled), you can do without the keymap
file. I place this file in /usr/local/etc/ here, but that's one of the
script settings I mentioned above as changeable. This file has control
characters in it, so I'll have to attach it encoded. I'll use UUE, which
most clients should have no problem with.
(It's worth noting that the other xorg key modifiers, alt and winkey, get
"lost" in the interface between xorg, konsole, and the shell. So using a
bash script, the only thing I know well enough to hack this up in,
unmodified, shifted, and controlled, are the only reliable options. Even
then, a few of them are "reserved". ^C ^J and ^M are SIGINT, linefeed
and carriagereturn respectively, and cannot be used as hotkeys.)
I'll also post a couple example menu files.
So four posts should follow, one each for the hkm menu script, the
hotkeylookup.lst keymap file, and two example user menu scripts.
