Design Keyboard Shortcuts

Alt+Ctrl+N - Looking at the XML for an Individual Object

In Design, if you select an object on the canvas or in the FE, then you can hit Alt+Ctrl+N, and you will be rewarded with the XATW XML that corresponds to the selected object.
It could be useful to look at the rich text encoding of a label, especially, simply to see if it is pure plain text or has some rich text. It can resolve some puzzles about hidden-in-rtf typeface usage. It's also a nice source of simple, well-formatted rtf for test purposes.
Anyway, you might want to get a quick look at the to-the-metal encoding of your design object(s). You can select multiple objects, or a group or pane or something and see the XML for all that you have selected. Of course, there is always "Tools">"View Form as XML" to really quench your thirst, but that can be an overwhelming firehose.

Ctrl+Shift+E - Save Image

One of the great things about DocOrigin is that images used in the Design are kept in the Design file. After years and years with a previous product where you always had to go on endless searches for the graphics files that went into a form design, what DocOrigin does is a true blessing. This is so handy for sharing and indeed for providing collateral to your support organization. They have the images, they don't have to come back to bug you for them.
You can find them in base64-encoded format in the XATW file. With effort you could copy that text out of there, convert, ..., but hey, just select the image and hit Ctrl+Shift+E and Design will offer to save that graphic in an appropriately typed (.jpg, .png, ...) file. Now you have it, you can use it in a new version of the form. You can avoid Form Verification Report errors that say the images aren't where they are expected to be.

Alt+X - Convert HEX Value to Unicode Symbol

Know any good Unicode characters? Sometimes it can be a head-scratcher to figure out how to enter them into a label's text string. If you know that special character's Unicode hex value it is a breeze. You type in its exactly 4 hex characters and then hit Alt+X. For example, suppose you want the division symbol, no not that one, this one: ÷. Its Unicode value in hex is 00F7. If you type 00F7 followed by Alt+X, you will get that ÷ symbol as sweet as anything.

Ctrl+G - Manage Object Tags

This is just a normal accelerator key that you can see on the menu. It is used for editing object tags. It's mentioned here because people don't always get into using object tags right away, but then when they do they may want to use them a lot for PDF/UA or barcode options or whatever has been dreamt up by the user. So knowing Ctrl+G can be a real timesaver. See PDF/UA tagging.

ALT - Reuse Previous Object Tool

In Design you select an object tool from the toolbar, e.g. field or text, ..., and then you place that object on the canvas. If you want to reuse that same tool to place another one on the canvas, you don't have to explicitly reselect it from the toolbar. Instead, you can just hold down the ALT key and you will see that your cursor changes to the previously selected tool's icon. This might well speed up your work.

ESC - Toggle Between Text and Object Edit

If you have a text label selected (i.e. with pick handles around it) you can hit ESC and thus go into text-editing mode. Conversely, if you are in text editing mode in a text label, you can hit ESC and you will leave test editing mode and have the text object be selected with pick handles around it. This is an essential skill.

Ctrl+Shift+A - Select All Objects in Pane

I've often wanted to move all the objects in a pane. If you select just one object in a pane, you can then do Ctrl+Shift+A and it will extend the selection to include all the objects in the pane. Have at! You can then use the arrow keys to shift them around a bit. Or you might apply a gang update using the modeless property dialogs. Handy.

F5, F7, F8 - Preview

You can click on the PDF or HTM toolbar icons, or use F5 or F7 instead. Also F8 for Merge Test. When you use these it applies whatever options were used most recently. If you want to supply new options, use Ctrl+F5, Ctrl+F7, or Ctrl+F8. You would then get the usual dialogs to set the options before doing the 'preview deed'.

Ctrl - Line on a Diagonal

When you want to draw a line that is not horizontal or vertical you can: select the line tool; hold down Ctrl; and draw a diagonal line.
