General Anaconda help To navigate the installation dialogs, use the Left, Right, Up, and Down arrow keys. Use Tab, and Alt-Tab to cycle forward or backward through each widget on the screen. Most screens display a summary of available cursor positioning keys along the bottom. To "press" a button, position the cursor over the button (using Tab, for instance) and press Space or Enter. To select an item from a list of items, move the cursor to the item you wish to select and press Enter. To select an item with a check box, move the cursor to the check box and press Space to select an item. To deselect, press Space a second time. Pressing F12 accepts the current values and proceeds to the next dialog; it is equivalent to pressing the OK button. Caution Unless a dialog box is waiting for your input, do not press any keys during the installation process (doing so may result in unpredictable behavior).
