Simply grabs QR code from screen and copies decoded text into clipboard.

Just launch QRab, make QR code visible on the screen
and hit 'GRAB!" button - QR text lands into clipboard.

Decoded text can be replaced in-between - this is fully configurable,
so i.e.: if there are tab characters it can be easily pasted into spreadsheet row.

It is crossplatform (Linux, MacOs and Windows)
