I set it up like this. It is convenient. Thanks.

Done. After doing the following, $mod+ctrl+1 switches alternately between the window marked 1 and the current window. Convenient! You work fast!

Thank you

So the windows class was for specifying the name of the application in X? I was mistaken. Wanting to memorize the window is the same as what I mentioned above, the concept of mark. It is good to know that this is feasible with the standard sway functionality. My apologies.

I think you suggest having another switch-to-mark-or-urgent-or-lru-window command which you can call like swayr switch-to-mark-or-urgent-or-lru-window 2 which would switch to the window with mark 2, or if that doesn't exist or is already focused, switch to the last recently used window?

Yeah, Looks good👍

I have been able to memorize and switch the switch target by the following with the help of sway's irc people through trial and error. There seems to be a concept called mark.

~/.config/sway/config

It would be useful if this mark could be the target of switch-to-urgent-or-lru-window, but what do you think? I imagine that this would allow for the task1 and task2 functions you mentioned in Ticket #13.

I'm sorry. The title was wrong. I can't seem to edit it from me, so please change it below if you can.

Window Class Specification: switch-to-app-or-urgent-or-lru-window

Hello.

The description of switch-to-app-or-urgent-or-lru-window is as follows

switch-to-app-or-urgent-or-lru-window
    Switch to the given app (given by app_id or window class) if that's not currently focused.  If it is, switch to the next urgent window (if any) or to last recently used window

I am wondering if it is possible to memorize this window class and make it the target for focus switching.

Is the window class here the same as the one obtained with the following command?

swaymsg -t get_tree | jq -r '..|try select(.focused == true)'

I am trying to achieve the following, but I am having trouble switching focus.

~/.config/sway/config

bindsym $mod+alt+ctrl+1 exec ~/.config/sway/window_id_set_or_switch.sh 1 set
bindsym $mod+alt+1      exec ~/.config/sway/window_id_set_or_switch.sh 1 switch

~/.config/sway/window_id_set_or_switch.sh

#!/bin/bash
KEY=$1
COMMAND=$2

if [ "$COMMAND" = "set" ] ; then
    swaymsg -t get_tree | jq -r '..|try select(.focused == true) .id' > /tmp/sway-window-id_$KEY
elif [ "$COMMAND" = "switch" ] ; then
    WINDOW_ID=$(cat /tmp/sway-window-id_$KEYNUM)
    echo $WINDOW_ID
    swayr switch-to-app-or-urgent-or-lru-window $WINDOW_ID
fi

Am I misunderstanding something?

It's done! Very comfortable. Thank you!

The following had the same result

$ swayr -- switch_to_app_or_urgent_or_lru_window org.qutebrowser.qutebrowser
$ swayr -- switch_to_app_or_urgent_or_lru_window qutebrowser
$ swayr -- switch_to_app_or_urgent_or_lru_window

Thanks. I was able to build it.

I can't get execution to work. Am I writing the command incorrectly?

Sorry I'm tripping over the basics, where is the address of the source? I rewrote the following PKGBUILD for swayr-git on Arch Linux, but I can't makepkg -is
