Basic inline editing has been added to Adobe CQ 5.4. To access this functionality, drag the BC Text Component from the Sidekick to a drop area ("Drag components or assets here"). Click once on the BC Text icon, wait a second, and click on it again. This slow double click will bring up the inline editor with a solid green line around it.
The editing toolbar is located at the upper part of the screen.
PLEASE NOTE: Once your edits are complete, click outside of the component so that the green line disappears. Then activate your page as necessary.
If the Inline Editing function is still active (green line appears) when you activate your page, any changes you've made will not be included in the activation and will not appear on your published page. Your changes will not be saved until the green border disappears.
