What are long press shortcuts?
Droid Scan 5.4 introduced long press shortcuts to streamline common tasks for experienced users. They are alternate actions that occur when you long press certain buttons.
To see how it works, just long-press the Import button (hold it down until you receive vibrate feedback), and you'll go straight to the Android Gallery (assuming that is the source you selected the last time you made an explicit choice).
Here is a summary of all shortcuts...
Import, Capture, Convert, Share JPEG, Share PDF, Export to SD Card:
When you long press one of these, a choice from the last time the the feature was used will have been remembered for you and will be chosen automatically, skipping a chooser screen.
In Remove, the meaning of long press is slightly different: it intensifies whatever delete mode is currently set, so that in normal mode, expunge is turned on for this time only, and in expunge mode, the confirm dialog is skipped completely (so use this feature with caution).
