In a sheet's card view there's a shortcut ('Enter') to open edit form for that row. There's no such shortcut or option in standard grid view or a report which is the main working mode for me.
Currently the only option I know of is to click on the row actions button and select 'Edit'. This is a lot of manual clicking considering I'm editing around 20+ rows daily.
Suggestion: create a shortcut that would allow entering edit mode of a row from sheet's grid view or a report's grid view.
Alternate suggestion: make double-clicking row number (i.e. the block of space where the row number is located) to enter edit mode of that row.
