* Left mouse-button on left button: Close the window.
* Right mouse-button on left button: Minimize the window to the height of the title-bar, if the window is already minimized, restore it to its previous size.
* Left mouse-button on right button: Move the window.
* Right mouse-button on right button: Enlarge/reduce the window.
A window can be brought to the foreground simply by clicking on it.
You can switch between levels currently loaded in memory using the `Level' button in the `Buttons' display.
Using the keyboard, the menus can be reached by pressing `Alt+letter', where letter is the one underlined in the menu name. Thereafter, the individual sub-menus or menu options can be reached by pressing the underlined letter or by moving the cursor up/down. Select the option by pressing `Enter'.
At the right-hand side of the menubar is the name of the level which is currently being edited.
Using the keyboard, options can be selected via cursor left/right within a window (the current window-field is red-framed). In this case `Enter' simulates the left mouse-button and `Shift+Enter' the right. It is only possible to change between the main mode windows via the keyboard (see also Section 4).
Sometimes two special pop-up dialogue buttons are also displayed:
* The "List button" (as with Load and Save): The List box displays a collection of words (e.g. filenames) sorted alphabetically in descending order. An item can be selected with `Enter', and you can initially choose the file name with the cursor, left/right and `Home' and `End' keys. If the list is very long, pressing the initial letter of the desired word places you at the first word in the list starting with that letter. Pressing `Enter' selects that corresponding word. By pressing `Esc' you can undo the choice of a word.
Translators Note:
This level-loading example shows why using a mouse is easier ;-) :
`Alt+F', L to load, press cursor-down four time to move the red frame to the level names, then press Enter to "activate" the list of names. Now press `y' to get to the levels starting with `y'. Move the box with the up/down cursor keys to get to YELLOW3.RL2. Press spacebar to select the level name. Now press cursor-up until the red-frame is back on the OK button. Press Enter.
* The Text button: In a text input field there is a special function. You can, after selecting the field, remove the contents of the field completely using `Shift+Del' and otherwise move around normally with cursor keys etc. and enter text. If you reach the right edge of the field, the text scrolls further to the left.
