Change "Transpose by key" to "Transpose to key"
Currently the transpose menu offers "Transpose Chromatically" with sub-options "By Key" and "By Interval". Transposing by key seems non-standard terminology and does not reflect what actually happens, which is that notes are moved to their equivalent pitch in the target key. The important word in that description is "to". It would be better if the sub-option was relabelled as "To Key"
It would also be useful to users if it was clarified either within the label or within a tool-tip that the target key is specified at concert pitch (rather than the written pitch for a transposing instrument).
