163You can disable the perl extension completely by setting the
164\&\fBperl-ext-common\fR resource to the empty string, which also keeps
165rxvt-unicode from initialising perl, saving memory.
166.Sp
167If you only want to disable specific features, you first have to
168identify which perl extension is responsible. For this, read the section
169\&\fB\s-1PREPACKAGED\s0 \s-1EXTENSIONS\s0\fR in the @@RXVT_NAME@@\fIperl\fR\|(3) manpage. For
170example, to disable the \fBselection-popup\fR and \fBoption-popup\fR, specify
171this \fBperl-ext-common\fR resource:
172.Sp
173.Vb 1
174\& URxvt.perl-ext-common: default,-selection-popup,-option-popup

177This will keep the default extensions, but disable the two popup
178extensions. Some extensions can also be configured, for example,
179scrollback search mode is triggered by \fBM\-s\fR. You can move it to any
180other combination either by setting the \fBsearchable-scrollback\fR resource:
