This site is designed to take advantage of CSS. If you are seeing this, CSS must not be available or enabled in your browser. Everything should still work, but won't be as pretty. :)
The checking of products can be halted with
[Control]+[Alt]+[Shift].
The alerts in which various products or the Version checker
output warnings and messages can be operated with [Tab] and [Space].
The Version checker recognises product items already loaded,
kicks them out itself during checking, and notes their order so that
after finishing work it can reload them automatically in the same
order.
Despite this is may be sensible to kick out all other product
items (particularly modules) before launching the Version checker, so
that all product items can be loaded and recognized.
