Hi, in a large-size perl/Tk program we are adding tags. Sometimes there are tens of thousands of tags to add, and this can take a lot of user real-time. Our window has a status bar, so I'd like to have something in it like,
Adding 1500 of 37885 tags. Press 's' to stop adding tags...
and have that update every 500 tags.
My question is, how can I detect the user entered 's' at this point in the code? I thought of adding a key binding, which I guess is the only way to do so, but would this intercept the user, say, typing a filename containing a 's' in a dialog box? In that case, is there a way to enable the key binding at just the point I need it, then disable it at the end? Or do I have to use something more unlikely, like CTRL+S?
Or is there a better way? Online searches have not been fruitful. Thank you!

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
