So, just like most people it happens that my memory for shortcuts and commands is kind of bad until it gets into muscle memory, but since it is just painful to have a fancy configuration in vim + tmux + urxvt without knowing by memory its hundreds of shortcuts I was thinking if there is any practical way to store the shortcuts and assign tags to them or a description, and be able to look them up.
I mean, anything similar to Zeal/Dash (or this: http://devdocs.io/).
Note that I mean a custom made index with custom entries, not anything like a vim man page, or a Dash docset.
Also as a side note, I'd like to know how do you people get past the burden of starting to use those programs without knowing a lot of commands and key combos. Since this is a side question yet slightly related, don't answer for this, use the comments, or annex to the answer. Thanks.
