I don't agree ! CTRL+Zoom is a common shortcut on whole operating systems, except MacOSX because... think different.

Here's my two cents, we keep actual behaviour:

• drag to move train on GET
• CTRL + drag to move chart (all charts)
• CTRL + mousewheel to zoom (all charts)
• CTRL + SHIFT + mousewheel to zoom horizontally (all charts)

For MacOSX, we should add a test to detect the OS and adapt shortcut. I'm not very familiar with MacOSX common shortcuts, but I think that Cmd is used in place of CTRL for the same shortcuts ? To be defined.

If test for OS is too heavy to be done inside a page, we could do it once for all in the head of the app and adapt shortcuts globally.

Is there an agreement on @nicolaswurtz 's comment here ? Can we assign this issue to somebody or does it need more discussion ?

Will be fixed with the GET refacto
