I have created a grid with Architect. I have about 30 columns, about 20 are editable columns. I am using rendering to caluclate two column values from data entered, a beforeedit to conditionally skip some columns for edit and getRowClass to display when some cells have invalid data, based on values in another cell. The movement from cell to cell with the TAB key when keying data is a little sluggish. Any suggestions on things to avoid doing when using a cell edit grid to make things faster or things to do?

They are comparing this to movement and editing in a spreadsheet.

Also is there any way to capture the key strokes and buffer them?
