Edit mode

Starting and finishing/canceling cell edit mode by keyboard works just in some cases. There are currently these limitations:

• regular cell, create for example Decision Table expression, there will be a regular cell under input-1 containing value -. If you start editing such a cell and will try to cancel edit mode by pressing escape, nothing happens
• select boxes in header cells popups, user can cancel context menu of header cell by pressing escape, however if an selectbox selection was changed, before, such change is not canceled
• input boxes in header cells popups, if user change column name of a decision table input column, then he press escape, then column is correctly not renamed, however if the menu is reopened, the new value is stored there

Acceptance criteria

• Enter commit changes
• Click outside commit changes
• Escape cancel changes
• Escape for header cells (context popups) keeps the value in input/select elements unchanged
