keys? or characters?
the Unicode value for ASCII Escape is 0x001B
what is/should be stored on file will depend on how the file's been
encoded
UTF-8 will store the character as the 8-bit quantity 0x1B
UTF-16 will store the two 8-bit quantities 0x00, 0x1B (but not
necessarily in that order -- it depends on your Endian properties)
ctrl-E is/was ENQ, and has the Unicode value 0x0005
ctrl-S is/was DC3 (typically, stop scrolling) and has the Unicode value
0x0013
ctrl-W (if that _is_ what you're using) is/was ETB (was that End Text
Block?), and has the Unicode value 0x0017
