Context-specific cursor duplication

[Stan15]

Describe this feature in detail

based on where the user's cursor currently is in a measure (it's distance from measure start) have a keyboard shortcut which duplicates their cursor across all measure lines in that measure, making sure that they all have the same distance from the measure's start.

example: ( the "I" is the cursor)
E|-----I-------|
E|-------------|
E|-------------|

shortcut pressed

E|-----I-------|
E|-----I-------|
E|-----I-------|

this would be even more helpful when there are unevenly aligned measure lines.
example: ( the "I" is the cursor)
H1|------------|
MD|-----I-------|
C|-------------|

shortcut pressed

H1|-----I-------|
MD|-----I-------|
C|-----I-------|

Reason for feature

This allows for higher-speed editing, increasing the duration between notes in the measure without having to count how many dashes and notes come beforehand.
