Post subject:  No-Op: how to delete op symbol?

If I accidentally place an operation symbol into a cell, how do I clear it?
I know about Shift+Left; I mean, via the number pad.
I've already tried pressing the same symbol twice; applying the Eraser; tapping the Undo button.

The puzzle in question is my current bonus puzzle, so unfortunately I cannot provide the link.

Try entering another symbol or the appropriate one......don't bother trying to delete it

Beaker is correct about ignoring the wrong operator until you are sure of the correct one.

Two other possibilities:

Write down, or print a copy of your work. This will save yourself the effort of repeating your work.

A) Clear the puzzle completely using the circular arrow. You will get a pristine copy of the puzzle

B) If you saved the puzzle before you made the error, restore the saved version.

I usually save a screenshot.

Anyways, I guess this topic is more of a “feature request” than a “bug report”. After all, it seems to be a missing button, not a non-functional button [confused]

Exactly, it's one of those small things I'll add to a list :-)

Another one I noticed: you can enter 10, 11, 12 as guesses in a 12x12 puzzle with Shift + a, b, c,
but not with Shift + 1-0, 1-1, 1-2
(even though you can enter 10, 11, 12 as a solution by pressing 1-0, 1-1, 1-2) [glare]

Why, that's OK, I like the way it is.
Shift+1-2-3-4 would be ambiguous: how will the game understand whether your guesses are {1,2,3,4} or {12,3,4}?

// One more nitpick: in a No-Op, if I hold Shift and press some digits to input my guesses and then press the right arrow (without releasing Shift), I expect to move to the adjacent cell (this is what happens with normal puzzles), but instead the operation symbol gets modified.
Though maybe it is a normal behavior and we are supposed to release Shift before moving.

Interestingly, if there is a 'full size' 1 in a cell and you type Shift + 0, 1, 2 then it becomes a guess of 10, 11 or 12. Not very useful if you need to enter more than one guess higher than 9 and quirky to use anyway. I've only discovered that by accident and don't use it purposefully for solving.
