PhpStorm 2020.2 Help

Documentation tool window

The View | Tool Windows | Documentation menu option appears only when you use the tool window for code documentation by default.

Out of the box, PhpStorm shows code documentation in a popup as you hover the mouse pointer over symbols in the editor. You can change the view to use the tool window by default: press Ctrl+Q to open the popup and then press Ctrl+Q again.

  • Adjust Font Size: display a slider for changing the font size.

  • View Mode: by default, the tool window is attached to the edge of the main window and is always visible. You can change the view mode, for example, to make it visible only when active or to detach it from the tool window bar.

  • Move to: select where to attach the tool window.

  • Resize: adjust the size of the tool window.

  • Remove from Sidebar: close the tool window. To reopen it, select View | Tool Windows | Documentation from the main menu.
