[Feature Request] Support multiple cursors

[hkcomori]

Is your feature request related to a problem? Please describe. Multiple-cursors allows me to select multiple strings at once. When multiple strings are selected and some formatting is toggled, it affects only the first string.

Describe the solution you'd like I want to apply formatting to all selected strings.

Describe alternatives you've considered Currently, I applies formatting to each string one at a time.
