I would overload the first portion of your resume with as many keywords related to the stacks you're familiar with because it's not like humans are reading these anyway.
Do not do this, but if you are, be sure to include Excel, Word, Windows, Outlook, and TCP/IP. Adding TCP/IP lets them know you're a real technical person.
Most automated scoring of a resume compares your resume to the job posting you're applying for. The closer the match the higher the score. You should be tuning your resume for each job and while using the same words and phrases in the job posting.
