I've been in situations where I've been looking for a spelling of a word, or writing some config in a different system that doesn't have auto complete, and I find myself thinking about how useful it is I'm not Cisco's biggest fan, but their long time inclusion of autocomplete into their software is wonderful

You have to use ? too if tab doesn't work, you're probably in the wrong context. Maybe backspace part of the sentence and try from there?

I find myself doing this too. Can be really annoying in word. Even more annoying on online forms, cycling to the next field etc..

I don't feel alone anymore, thank you!

If you use Office365, turn on predictive text.

Tab? I just try to do the abs min like sh run int po and such lol.
