Taking screenshots in PEM or with temporary informations on the display

Taking screenshots on the WP43 is done with the SNAP operation. However in PEM, SNAP is entered as a program instruction (which is good) so there is no way to take a screenshot of the display. Furthermore if there is a temporary information on the display, pressing and releasing the g key (before pressing the f key for SNAP) will clear the temporary information preventing it to be on the screenshot.

The solution on the HW calculator is to add the support of the DMCP virtual screenshot key code generated when SHIFT and DISP are pressed simultaneously. On the WP43 this key combination is g+DISP.
