unable to parse config file, = expected send, on_release, shorthand_allow, or key_range

[evanescente-ondine]

It's my first installation/configuration. I'd like to know if it's a bug or the config is wrong:
~> [2025-10-25T23:40:27Z ERROR swhkd] Config Error: unable to parse config file
[2025-10-25T23:40:27Z ERROR swhkd] --> .config/swhkd/swhkdrc:1:23

= expected send, on_release, shorthand_allow, or key_range
Simple-Wayland-HotKey-Daemon 1.3.0-dev
Linux 84-47-09-37-40-35 6.12.43+deb13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.12.43-1 (2025-08-27) x86_64 GNU/Linux

the config goes like this:
super + {F4,F10,F2,F5,shift + F5}
doas loginctl {poweroff,hybrid-sleep,suspend,reboot,reboot --firmware-setup}
super + {Return,asterisk,shift + asterisk}
{footclient broot,footclient,foot}

And if comment out the first two lines, the same message goes about the second and third lines. When comparing what I read in the official documentation I just can't see the difference.

Thanks for your help.
