HTML5 offers many new input types which were not available in previous versions. Smart phones and tablets have limited screen real estate and the interfaces need to be sensitive to touch which requires more space than a mouse pointer. These interfaces require users to switch between keyboards to input characters. HTML5 forms allow web designers to make their sites more user-friendly by offering preselected keyboard such as a date picker for date field, @ and . symbols in the keyboard for emails, and numeric keyboard for numbers.
Microsoft Windows offer many simple keyboard shortcuts. If you use computer as much as I do, you would find that these commands are easy to remember and simplify life a little bit. The symbol + in the table means that you have to press those keys together. win is the windows button just to the right of ctrl with Microsoft Windows logo. The keys are typed in CAPS to increase readability e.g. one and the letter can be confusing is lowercase but not when L is written in uppercase. The commands are NOT case sensitive.
