 text into various other formats/action (such as uri unescaping, perl
 evaluation, web-browser starting etc.), depending on content.

 It should either return nothing or a string and a code reference. The
 string will be used as button text and the code reference will be called
 when the button gets activated and should transform C<$_>.
 The following will add an entry C<a to b> that transforms all C<a>s in
 bottom. C<Escape> leaves search mode and returns to the point where search
 was started, while C<Enter> or C<Return> stay at the current position and
 additionally stores the first match in the current line into the primary
 selection.
+The regex defaults to "(?i)", resulting in a case-insensitive search. To
+get a case-sensitive search you can delete this prefix using C<BackSpace>
+or simply use an uppercase character which removes the "(?i)" prefix.

 B<Shift-Right> will switch to the tab left or right of the current one,
 while B<Shift-Down> creates a new tab.
