I would like to be able to compare files or directories by multiple-selecting them and then right clicking (for example, if there was a "compare" option in the context menu).
On Ubuntu with Nautilus, I would install the package nautilus-compare. How can I get this ability in Xubuntu? (in Thunar in Xubuntu – I don't mean by installing Nautilus)
The comparison program I use is meld, but a general answer would be most useful.

The accepted answer is very close, but not entirely correct.
In order to compare multiple files / directories, create a new Action with the following command:
Only using "meld %f" will only allow you to open one object in meld.
See attached screenshots for an example.

I would have made this a comment, but I am not yet allowed to do so.
