Product Questions

I have a user that accidentally deleted a document is there a way to get it back?

We purchased a plan from LucidChart so that we can shared documents and we can; but there does not to be any way to print a shared document or save it to PDF.  Is there some way to do it?

I have three questions while drawing maps to illustrate  human metabolism  1) How can we include Greek alphabet letters in our drawing 2)How many layers can we have maximum? 3) We want to draw an arrow that has two lines crossing the arrow (see attachment). We tried to use two lines but at the place where the lines intersect with the arrow the line is no longer straight. That's not what we want. We also try using equation marks but the background of the equation is not transparent. it blocks part of the arrow.  Not sure how to proceed   Thanks! Screen Shot 2015-04-15 at 4.04.20 PM.png

Does such a list exist? More specifically I was wondering if there was a shortcut to go from one selected box to selecting the one next to it? And while we're at it is there a way to select the text inside a box without having to use the mouse double-click?

How can I rotate a window?

Would be nice to have an arrow option in Lucidchart for process flows so you could create a bidirectional line with both a head and tail arrow.

I added a shape and typed in some text.  I would like to change the shape to something different but retain the text.  Is that possible?

I am using the online version and I cannot find where to disable line jumps. I have multiple intersecting lines and I need them to not have jumps. Can someone please point me to where I can disable this?

I would like to be able to place a border around an image. Not a border placed floating around it (like a container) but one that is stuck to the image. Images look better this way.

Can someone please provide details regarding the same.

It seems like there's no way to lock aspect ratio while resizing an object.

I've found a few hot keys I didn't know about while browsing through the forums (Like ⌥ + mouse to move canvas and ⌘+G to group) and a few are mentioned in UI menus (L for line draw) but is there a master list somewhere?
