Hebrew: General question about location of shortcut indicator "&" and reading direction

Hello,

I am upstream maintainer of "backintime". I don't know nothing about 
Hebrew just that it is a right-to-left language.

I try to understand something about the position of shortcut indicators 
("&") used in GUIs. Copy and pasting test is hard in this topic. So let 
me also point you to a Dicussion post at Weblate including some nice 
screenshots.

The term "&Options" is translated into "אפשרויות". Weblate do know the 
diff between RTL and LTR languages. It displays the "&" on the right 
side of the string.
So the "first" (from the right) letter is used as shortcut. I can 
confirm this when looking into the original GUI. That latter is 
underlined.

But looking into the raw po file (using vim) The "&" is on the left 
side. That confused me.
And even when I try to copy & paste the translated string from Weblate 
into this email (using posteo webfrontend dovecot) the "&" moved to the 
other end. "&אפשרויות"

So the final result in the GUI is fine. So there is no real problem. I 
just try to understand why it happens like this.

Kind
