When I add the tag "howto" to the "Keywords" field

Add a tag to a tags field by typing it: an existing tag is picked, a new one is created.

Examples

When I add the tag "howto" to the "Keywords" field
When I add the tag "release" to the "Keywords" field
When we add the tag "events" to the "Keywords" field
And I add the tag "howto" to the "Keywords" field
And we add the tag "release" to the "Keywords" field

Pattern

When(/^(I |we )*add the tag "([^"]*)" to the "([^"]*)" field$/, …)
