Hello,

In p9p's rio there is a possibility to cycle over windows with left_alt-tab.
Has anyone thought about / managed to add some more shortcuts, e.g.
such that would run a program like dmenu?
(Do you start all your programs from a terminal?)

Thanks
Ruda

cinap has a patch for that in /n/sources/contrib/cinap_lenrek/rio.c, I don't remember
the scapes, I think it was ^n or ^m.

I put some additional keyboard functionality into w9wm at one point,
it's not that hard. Look at /usr/local/plan9/src/cmd/rio/key.c:44,
figure out what key presses you want to handle, then do a fork+exec or
whatever floats your boat.

You might also find 9menu handy, although personally I don't like
using it in p9p rio because rio doesn't pass focus clicks through to
the client, meaning I have to click twice (annoying). I just use a
terminal to start programs.

I'm using p9p rio right now, but that's because I cycle through about
a half-dozen window managers a year in search of WM nirvana. I love
using rio on Plan 9, but I'm not entirely convinced it is best-suited
for the way I use Unix. Some day I may write my own WM, but today is
not that day.

Ok. For anyone interested, I changed my p9p rio key.c:
*** key.c_orig 2012-11-03 18:59:41.040071847 +0100
--- key.c 2012-11-04 10:41:27.853606153 +0100

{
int i;
int tabcode = XKeysymToKeycode(dpy, XK_Tab);
+ int tcode = XKeysymToKeycode(dpy, XK_t);
+ int rcode = XKeysymToKeycode(dpy, XK_r);

for(i=0; i<num_screens; i++){
XGrabKey(dpy, tabcode, Mod1Mask, screens[i].root, 0, GrabModeSync,
GrabModeAsync);
XGrabKey(dpy, tabcode, Mod1Mask|ShiftMask, screens[i].root, 0,
GrabModeSync, GrabModeAsync);
+ XGrabKey(dpy, tcode, Mod1Mask, screens[i].root, 0, GrabModeSync,
GrabModeAsync);
+ XGrabKey(dpy, rcode, Mod1Mask, screens[i].root, 0, GrabModeSync,
GrabModeAsync);
/* XGrabKey(dpy, pgupcode, Mod1Mask, screens[i].root, 0,

/* XGrabKey(dpy, pgdowncode, Mod1Mask, screens[i].root, 0,

/* XGrabKey(dpy, altcode, 0, screens[i].root, 0, GrabModeSync,
GrabModeAsync); */

int tabcode = XKeysymToKeycode(dpy, XK_Tab);
+ int tcode = XKeysymToKeycode(dpy, XK_t);
+ int rcode = XKeysymToKeycode(dpy, XK_r);
+
if(e->keycode == tabcode && (e->state&Mod1Mask) == (1<<3))
alttab(e->state&ShiftMask);
+ if(e->keycode == tcode && (e->state&Mod1Mask) == (1<<3)) {
+ if(fork() == 0)
+ execl("/home/ruda/bin/xt", "xt", (char *) 0);
+ }
+ if(e->keycode == rcode && (e->state&Mod1Mask) == (1<<3)) {
+ if(fork() == 0)
+ execl("/usr/local/bin/dmenu_run", "dmenu_run", (char *) 0);
+ }
XAllowEvents(dpy, SyncKeyboard, e->time);
}

which now opens xterm (xt is my xterm with unicode locale on) on
pressing alt-t and runs dmenu_run (related to dwm) on alt-r.

I missed these two shortcuts heavily.
(warning: I just added the lines by means of observation; I do not
really know what stands behind those XGrabKey and alike functions.
Nonetheless it now does what I want.)

Also I want to ask if someone noticed that p9p rio for some reason
precludes e.g. shuffling of firefox' tabs (both within one window and
between windows). Running twm instead of rio helps in this respect.

This breaks nested rio.

Yes, since the program takes over the window anyway.

It is probably much easier to use xbindkeys for that.

Oh, gross. Never mind.
