[Plugin: List category posts] Exclude current post

Hi everybody.
I installed the plugin [List category posts] (version 0.18.3) to include at the bottom of a post a list of ‘similar’ posts (that is, posts that have same category of the one currently showed).
I used the following shortcode:

[catlist id=XX numberposts=5]

where XX=is the category of the current post (eg. 29).
The result is the list of ‘similar’ posts, but that list includes the current one too.
So I tried this one:

[catlist id=XX numberposts=5 excludeposts=<ID_OF_CURRENT_POST>]

but I don’t know how to set the value <ID_OF_CURRENT_POST> at runtime.

Any help is appreciated.
