Adjust Text Frame With Type Tool
It KILLS me every time I input or type text in INDD and get the cursed overset text error, but I have to switch to the Selection Tool to reframe the text box, then switch back to the Type Tool and continue. PowerPoint and even Google Slides allow you to move your cursor near the boundaries and adjust the size of the text frame without switching tools.
What's more, switching to different tools while editing type is slightly annoying. Because you can't hit 'v' for selection tool, you either have to click the selection tool or click outside the text frame then hit 'v'. I'd love to see the type tool be able to adjust the text frame when you move the cursor to the corners and centers of the bounding box. I think any typographer and designer would be in love with this feature.
You can easily achieve this without the need to switch to the Selection Tool.
Hold down the Ctrl key (while you are in text edit mode or even when you are not in text edit mode or when the text frame that you want to resize is not even selected). When you hover the mouse over the text frame, you will see Resizing handles (shown as 9 solid points on the bounding box) – you can drag to resize the text frame.
Hope this helps.
