For simple interactive usage aliases go a long way, and with tab completion it gets really fast to write. For example, Invoke-WebRequest is iwr, Select-Object I think is just select. Some others are ForEach-Object which is %, and Where-Object can be ? Or where. Also, since PowerShell is case insensitive, you don't really need to use all those capitals - the worst you'll get is a warning from your editor, if it has PowerShell integration (around 99% sure about this)

It also has tab completion of parameters, so you can tab complete not just commands but things like -ExpandProperty too

I think you don't even need to type out the whole option, just the first few letters most of the time? I haven't used PowerShell in a bit, but I think if you have a command with a -Force option, but just type -f, it will go through as -Force, if and only if the command doesn't have any other options starting in f
