This code was most likely being written through the Copy-Paste method. It resulted in using IDC_KEYWORD3_BOLD_CHECK instead of IDC_KEYWORD3_ITALIC_CHECK. The warning looks a bit strange, telling us about the numbers '7', '7', '6', '7'. Unfortunately, a clearer message cannot be generated.

This suspicious code was found in Notepad++ project by PVS-Studio static code analyzer.
Warning message is:
V525 The code containing the collection of similar blocks. Check items '7', '7', '6', '7' in lines 576, 580, 584, 588
