When the cursor is in the parameter section of method call, the method signature is displayed in a bubble help window, with the text of the current parameter displayed in red.
The method call signature is placed directly under the left parenthesis line. If the call logic spans multiple lines, when you move to a subsequent line that is still within the call signature, the display is placed above the line with the left parenthesis. If the display includes multiple lines of user text and there is insufficient room to fit the full display, the text is truncated.
Press the ESC key to close the bubble help window.
