The SCHEMA:PATH part seems slightly wrong (singular vs. plural). Try:

schema=org.gnome.settings-daemon.plugins.media-keys.custom-keybinding
path=/org/gnome/settings-daemon/plugins/media-keys/custom-keybindings/custom1/

gsettings get "${schema}:${path}" binding
gsettings get "${schema}:${path}" command
gsettings get "${schema}:${path}" name

Although committing the feature to the Github repository has finished, the feature will be available for you when your instance updates the Lemmy version to 0.20, 1.0, or higher.

How about consult-history? https://github.com/minad/consult?tab=readme-ov-file#histories

If anyone has other suggestions to mitigate this

Firefox has “permissions.default.image” (link) option that disables image loading, but this Wikipage is very old so I’m not sure whether it works properly in current FIrefox.

What program are you using to write or edit the comments?

Some applications can’t display some Unicode strings like s̵t̵r̵o̵k̵e̵, so replacing Markdown element like ~strike~ with Unicode equivalent (s̵t̵r̵o̵k̵e̵ ) may not be a good idea if you want portability. I opened your post in text editors and noticed that neovim-qt drops s̵t̵r̵o̵k̵e̵’s combining characters (issue on Github) and just displays stroke instead of s̵t̵r̵o̵k̵e̵; GUI Emacs with my font settings (Noto) doesn’t combine the characters and displays s-t-r-o-k-e- (as I said, this may depends on font settings).
