Please post the whole output (it should contain “font” and “text propertires”), and run describe-char against the actual space-inserted assignment operator you found (not the newly created file), and finally, enclose the output with three backquotes. to format it properly.

Can you post the output of M-x describe-char on each character (“:”, space, “=”) here?

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

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.

I’d write a bookmarklet for that case:

javascript:
{
const name = 'ABC';
const d = new Date();
const year = d.getFullYear();
const month = d.getMonth();
const date = d.getDate();
document.activeElement.value = `${year}/${month}/${date} ${name}`;
void 0;
}

This bookmarklet inserts the desired text into the currently focused text box. Tested on Lemmy Web UI.

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