The original purpose of this task was to request that meta-E/meta-V worked as shortcuts to switch editors while editing a page.
However, a few days later, looks like these 2 shortcuts are already providing such a switch functionality.
The problem is that WT users expect that hitting meta//-V while editing triggers the "Show changes" action instead.
I do not have a suggestion for a better key.
