Outline: You can get an outline of what's in the current file in at least three different ways:
Clicking into the Outline textbox at the top right of the main window, or hitting Alt + Ctrl + N opens a drop-down menu that lists all function and class declarations: You can then just select which one to jump to, or — if there are a lot — start typing any text that may appear in the names shown; in that case, as you keep typing, the list becomes smaller and smaller as names are removed that don't match the text already typed until you are ready to select one of the choices.
Positioning the cursor at file scope (i.e. outside any function or class declarations or definitions) and having the Code Browser tool open: This also provides you an outline of what is happening in the current file, and allows you to select where you want to jump to.
Hovering the mouse over the tab for one of the open files also yields an outline of the file in that tab.
