Long-press Shortcuts

[ChristiduToit]

Long-press shortcuts are super useful in other apps such as Photoshop, really help to speed up workflows, and I thought it might be a great little addition to Affinity apps too. 
I'm sure you already know what I'm talking about, but just for clarity:
When you use a tool in PS, and press and hold a shortcut for another tool, you can temporarily use that tool until you stop pressing the shortcut.

For instance, if you're using the brush tool, you can press and hold "E" to temporarily use the eraser tool, which then automatically switches back to the brush tool as soon as you stop pressing "E".

This works in some cases in Affinity.

For example draw with Pen Tool, press Ctrl switch to Node Tool (correct node position or curve shape), release Ctrl - continue with Pen Tool.

@Pšenda 
I know about the quick 'edit' mode switch when using the pen tool - very handy!
Something similar is also available for the Pixel Tool, where when you hold Cmd (Mac) or Ctrl (Windows) to quickly transform the brush into an eraser (I this would actually be such a great tool for the normal brush tool too).

With what I mentioned, it's a lot more versatile, as you wouldn't be limited any any specific tool.
With the long press shortcuts (which would ultimately be very similar to the pen tool edit mode) I could be painting with the brush, quickly switch to the smudge brush tool, or eraser, or flood fill, or freehand selection, etc, and back to the brush with ease.
