A very useful short cut that I often don't think of is...
Start a new Sub anywhere, type 'Sub' then space key then TAB key.
A menu pops up, listing all possible event handlers names , click on your choice, another menu pops up listing the events for that handler.
Click on the one you want and a sub parameter template is automatically inserted after the Sub.
Then just change the handler name to you situation. Try it. You'll see B4XPagesManager, click, you'll see Appear, click again.
Then change 'EventName' to 'B4XPage', and you're all set. Happy coding.
