How to hide and show the main menu
The main menu has now moved from the top frame of REsearch to the left of the screen.
This is the Menu button. It is located in the upper right corner of the screen. You may toggle it to hide/show the menu.
Once the menu is hidden, you may move your mouse pointer to the left of the screen in order to activate and show the menu.
Simply move the mouse pointer to the far left of your browser. The menu will automatically open if it is currently hidden.
