If your screen is very small so you need every square-centimeter for displaying the buffer which you want to edit, ECB offers you a special layouts, where only the ECB-methods buffer is displayed on top or on left-side. Here comes what you should/can do to work best with ECB in such a situation:
ecb-layout-nameto layout-name “top2” (on top) or “left9” (on left-side)
ecb-toggle-ecb-windows(also available via the menu “ECB” and by C-c . lw) or
ecb-hide-ecb-windowsto hide the ECB-method buffer so you get all the place of your screen for editing.
ecb-show-ecb-windowsto make the ECB-method buffer visible if not already. If you want select a method/variable with the keyboard instead with the mouse you should read the section Using the keyboard in this online help!
The possibility of hiding temporally the ECB windows like described above is also useful for all the other layouts.
