Honestly, I think "int3" is better than "tp" as a part of the name.

"tp" doesn't say _anything_ to me, even though I understand it is
short for "text poke". But if you want to say 'text_poke", please just
write it out.

At least "int3" has some meaning in x86 context, unlike "tp".

So please either write out "text_poke" and accept that the names are a
bit longer (but a lot more descriptive), or use "int3" if you want to
save some typing.

PS. The casual meaning "tp" has in English everyday language is short
for "toilet paper".
