It is impossible to use ctrl + shift combinations in the terminal world. Shift makes an or with 0x20 and ctrl makes an and with 0x1f, so if you press them at the same time you are going to have something like (c | 0x20) ^ 0x1f == c & 0x1f. > C-Ins looked like a nice suggestion, even though we are not inserting > text into the application. I prefer the ctrl + shift for the reason I posted (they cannot be used in a terminal application) and because I would like to use ctrl + insert for an ascii mode sequence. Regards,
