<\body> When creating an environment like a theorem, an equation or a list, it frequently happens that one would like to change the environment . This can be done using the keyboard shortcuts and for cycling through the list of of the innermost tag in a direct or inverse manner. For instance, assuming that you are inside a theorem, pressing several times will change the theorem into a proposition, a lemma, a corollary, a conjecture and back into a theorem. The key allows you to cycle in the inverse direction: theorem>> conjectur>> corollary>> lemma>> proposition>> theorem. In the case of mathematical formulas, the shortcuts allows you to change an inline formula like +b=c> into a displayed formula like <\equation*> a+b=c while taking care of potential ``trailing spaces and punctuation signs''. also provides the shortcut for turning numbered environments into unnumbered environments and . This works for most common environments like theorems, remarks, tables, equations, etc. Notice that also turns an unnumbered itemize environment into an enumeration and , whereas allows you to cycle between the available kinds of list items (bullets, dashes, arrows, ). <\initial> <\collection>
