Case-preserved change selection

[leonlonsdale]

Forgive me if this already exists, but I've not found it yet, if it does.

The idea is to add a case preserving change_selection.

For example, let's say I am making a simple budgeting app in which I have a class Accounts. I create an instance, accounts. Within the file documentation / doc strings, both Accounts and accounts are referenced. Lets say I now decide that the name Accounts is not quite right - I now want to rename it to bills, to free up the name for a new Accounts class for bank accounts.

• using lsp rename doesn't work on both the class and its instances, and certainly not in the doc strings.
• using select all (%) and regex search (s) does find all instances of the word, but when I hit c to change, all instances of the word are replaced with the capitalisation of the new word; if I type 'billing' then Accounts becomes billing instead of Billing.

It would be cool if there was a case preserve version of 'c' when changing.
