By default, the quick documentation popup appears as you hover over code elements. You can configure the IDE to display the popup only after you explicitly invoke the Quick Documentation feature.

• Click in the popup and disable the Show on Mouse Move option.

• In the Settings dialog (CtrlAlt0S) , go to Editor | Code Editing | Quick Documentation and clear the Show quick documentation on hover checkbox.

  In this case, to view documentation for a symbol at caret, press Ctrl0Q or select View | Quick Documentation from the main menu. The documentation will be shown in a popup, but you can configure the IDE to display it in the tool window right away.

With the default settings, pressing Ctrl0Q (View | Quick Documentation) opens quick documentation in a popup. You can change the settings to view documentation in the tool window.

• In the quick documentation popup, click and disable the Show Documentation Popup First option.

• In the Documentation tool window, click the icon on the tool window toolbar and disable the Show Documentation Popup First option.

You can open a piece of documentation for a specific code element in the tool window and keep viewing documentation for other elements in your current file.

1. Place the caret at the required code element and press Ctrl0Q. If the popup appears, press Ctrl0Q again to switch to the tool window.

   The asterisk symbol (*) on the documentation tab means that the tab is not pinned, so its content will be replaced by documentation for another code element that you select in the editor.

2. Right-click the tab with the documentation in the documentation tool window and enable the Keep This Documentation option.

   After that, the current documentation tab will be pinned. You can return to the editor and view documentation for other code elements that will open either in the popup or in a new tab in the tool window.
