in MS Edge browser when adding a comment, Alt+e (to share with customer) does not work.

[JustDoWIT]

When adding a comment to a service desk ticket I have three choices at the bottom, Share with customer, internal and cancel.

When I hover my mouse over 'Share with customer' help text says, 'Press Alt+e' to submit this form'. 

When I hover mouse over 'Comment internally' the help text says, 'Press Alt+s to submit this form'.

When I over over 'Cancel', help text says 'Press Alt+` to cancel'

None of these 'Alt+ keyboard commands work.  We either need to remove the help text or get the Alt+ commands to work.  Thank you.
