Learning patterns/Use cheatsheeting in the form of a collapsible toolbox
What problem does this solve?
Many things are easily forgotten. Syntax of templates, wiki markup, special links etc are scattered everywhere in help pages and external tools are not included there. Topics heard in lessons, even more than twice, are easily forgotten even as bullets.
What is the solution?
A cheatsheet collapsing thematic toolbox can be put inside user's main sandbox (1-click reach), either as a link or embedded, depended on the use of VisualEditor inside the main user sandbox or not. Cheatsheet collapsing template can be embedded as pre-expanded.
Things to consider
You can use Template:Collapse-mobile to make collapsing boxes that are viewable on mobile phones.
