I can\'t find a solution (here and on the web) for simply selecting/inserting/deleting stuff surrounded by dots (a common case in development) :
someobje
I dont know any generic solutions. For select/delete/insert I use regular experssions.
:%s/\.some-property-with-hyphens\./.i-like-this-property./g
To just select
/\.some-property-with-hypehns\.
A more generic rule
/\.[\-a-zA-Z0-9]*\.
Hope this is what you are asking.
