Then you can define additional Auto-Type sequences by going to the Auto-Type tab in the entry, add a window association, leave the window title blank, then set the custom sequence to be {S:attribute-name}. Now your advanced attributes will appear in the pick list for Auto-Type.

Where exactly should I see the option to auto-type an additional default sequences? I created one with an empty title, but cannot see this additional sequence neither in the entry context menu, nor in the toolbar dropdown, nor in the Global Auto-Type dialog.

Also, the documentation does not specify whether spaces in the attribute name should be escaped in the {S:attribute name} syntax. Can you please suggest?

I've read https://keepassxc.org/docs/KeePassXC_UserGuide.html#_auto_type thoroughly.

If you leave the window title (empty) then the sequence will only show up when you do a SEARCH for the window in the auto-type select dialog. That is hyper confusing and this behavior makes no sense to me.
