These days I rarely use Excel 2003. But when I do open the trusty old software, I always look for opportunities to improve my productivity with it. And I am pleasantly surprised to find a shorter and faster way to turn off grid lines on spreadsheets in Excel 2003. (I like my spreadsheets without any grid lines, like a clean slate).
I usually go to Tools > Options > View Tab and then uncheck the “gridlines” checkbox.
This takes about 5 clicks and a lot of mouse commute. So much that I often feel like taking a detour for a sip of coffee. But the new and simpler method I found yesterday is to use the forms tool bar (which is turned on by default in my comp). In forms toolbar you find the “toggle gridlines” button which can quickly turn on / off the grid lines. See below:
