How to change bytes in IDA Pro Hex view?

While in IDA’s Hex View you can go to Edit->Patch Program->Change Byte, but I think this only lets you patch 16 bytes at a time. If you need to patch more bytes than that you can use IDAPython’s idc.PatchByte / idc.PatchWord / idc.PatchDword to change bytes in the IDA database.
