3.4 Viewing error messages ========================== To view error messages belonging to the current line, use the ‘flymake-display-err-menu-for-current-line’ function. If there’s at least one error or warning reported for the current line, this function will display a popup menu with error/warning texts. Selecting the menu item whose error belongs to another file brings forward that file with the help of the ‘flymake-goto-file-and-line’ function.
