It means that you have used a, well let's say a, "significant" word as a 
variable name (in this case a variable described as a parameter name).

What does that mean?

It means that within the scope of your declaration of that variable you 
cannot expect to use the native Key class to be operative. So Gambas is 
telling you essentially that "OK, you want to use one of my special 
names as your own variable name and instead of it referring to my Key 
class, then fine I'll just use your string variable. Fine, OK then I 
guess you know what you're doing."

In other words, as long as you don't refer to the native class within 
the scope of that procedure then everything will work as you expect.
