Meaning of the "green hook" at icons in Projects Pad

[_KK_]

Searching on Ranorex Website got no result.

Where can I find the explanantion of the Little Icons in Projects Pad in the user manual?
What is exactly the meaning of the green hook (see attachment)?

Although a get latest was done by VisualStudio after Opening the Rx app, this green hook is shown.
Does Rx store somewhere information about the state of a module if it was changed outside the source safe TFS?

Thanks in Advance for an answer.

Greetings

The little green tick mark? That means it's under source control and hasn't changed. It's a little red pling when the source file has been changed and not yet committed.

Many thanks to Stub,

in my case it indicates that there was a Change. But I dont know why there was a Change.
Before seeing this I did a undo in VS for TFS and also an undo in RX.
But it still Shows the tick after get latest with VS.

We investigated that there are Rx-Cache files on harddisk.
We deleted them and got latest again, but still this tick is shown.

?? Intergalactical interference??
