Every function can be assigned a shortcut It's an incredibly customizable and scriptable file explorer that allows you to fit it exactly to your workflow. Also expect having to whitelist it with anti-virus products, but the source code is open and you can build it yourself if you don't trust what you are getting. They often look at the APIs PH uses and use signature checks and other ways to block/discourage PH from using them. Unfortunately due to a personal dispute with a Webroot employee and Microsoft its signature ended up in antivirus databases, so don't expect any love from Microsoft.
Also I strongly suggest building the plugins extra repo, has some great ones, like a terminator plugin that can kill apps various user and kernel ways. Be sure to get the nightly/3.0 branch, the 2.0 branch is several years old. I'll suggest Process Hacker It is the ultimate Task Manger, open source, supports amazing plugins, and has tons of features that sysinternals Process Explorer lacks.
