Jira has a keyboard shortcut of Ctrl+Alt+S for form submit on Chrome Mac. It's awkward. Is there a way to change this locally? I am not the Jira admin.
Unfortunately there is no way to do this in Jira without third-party software for keyboard remapping, etc.
There was a suggestion/improvement submitted for custom keyboard shortcuts in Jira, but it was resolved as "No Fix" by the vendor.
Somebody asked a similar question and the answer provided an example user script to accomplish this. Their example uses GreaseMonkey in firefox but Tampermonkey should serve the same purpose in Chrome.
