Barcode scanning not obvious working

I am willing to put labels on my parts. Ideally I would have an option to scan for parts using a barcode or the like. However, I would need to know what exactly I put into the barcodes before I start printing hundreds of labels just to see the barcode is not working.

I think there are multiple way in general: One is to use the search field. The other is described in the wiki. The foremost has the problem that the search functionality for internal ids is non-functional at the moment (#924).

When trying to use the latter method, I do not get any useful results. I do not have a barcode reader that allows me to insert a hotkey automatically. So I need to manually press the hotkey then "type" the search string. Is this correct? I tried on the demo page to set the hotkey to <Ctrl><Alt><Shift><I> and added an action for key S in the table below. Saving and going back to the main parts view I do the following:

1. Press the Hotkey (aka <Ctrl><Alt><Shift><I>) and letting loose all 4 keys
2. Typing s767 and Enter I assume something should happen now and the part with number 767 should be highlighted or the like.

Does this happen for you as well or am I misinterpreting the intended use of the function?
