Auto-load keyfile when opening KeePass database from another KeePass database

Question

When I have a KeePass entry with the path to a second KeePass database as the URL I can click "Copy Password" and "Open URL(s)" and then paste the copied password into the password field of the "Open Database" dialog to open the second database file (or alternatively press Ctrl-C, Ctrl-U, Ctrl-V to the same end).

However, when the second database is protected by an additional master key file, I need to manually select that file, which is inconvenient. How can I make it so that the master key field is automatically populated when opening the URL to the second database?

Open the entry in question and go to the "Properties" tab. In the field "Override URL" you can specify a different handler for opening the URL of that entry. Load the key file via the commandline option -preselect.

Something like this will do what you want:

cmd://"{APPDIR}\keepass.exe" "{URL}" -preselect:"C:\path\to\your.key"
