 135  * screen reader it seems to jump to the cursor every time through the
 136  * mswin_charavail() loop in GetKey, and the timeout is this long. So we
 137  * just need to set it higher than we do in pine. If we understood this
 138  * we would probably see that we don't need any timer at all in pico, but
 139  * we don't remember why it is here so we'd better leave it.
