You can specify a list of keywords in a single file with its binary mask and use the search engine to find them.
The file format should be something like this:
$ cat token
token: Library token
string: lib
mask: ff 00 ff
token: Realtime
string: rt
mask: ff ff
Note that tab is used to indent the 'string' and 'mask' tokens. The first line specifies the keyword name which have nothing to do with the search.
[0x08049A80]> /. /tmp/token
Using keyword(Library token,lib,ff 00 ff)
Using keyword(Realtime,rt,ff ff)
Keywords: 2
29 hits found
Now you can move to the 'search' flag space and list the hits with the 'f' command.
[0x08049A80]> fs search
[0x08049A80]> f
...
Use the '/n' command to seek between the hits. Or just 'n' and 'N' keys in visual mode.
