Original GitHub issue: https://github.com/rivo/tview/issues/176

After the 990bc2ebcf commit to allow navigation in input fileds, I can no longer enter a colon. I have traced it down to the code starting here.

			modifiers := event.Modifiers()
			if modifiers == tcell.ModNone {
				ch := string(event.Rune())
				newText := i.text[:i.cursorPos] + ch + i.text[i.cursorPos:]
				if i.accept != nil {
					if !i.accept(newText, event.Rune()) {
						break
					}
				}
				i.text = newText
				i.cursorPos += len(ch)
			} else if modifiers&tcell.ModAlt > 0 {
				// We accept some Alt- key combinations.
				switch event.Rune() {
				case 'a': // Home.
					home()
				case 'e': // End.
					end()
				case 'b': // Move word left.
					moveWordLeft()
				case 'f': // Move word right.
					moveWordRight()
				}
			}

I changed it to the following and it works again.

			ch := string(event.Rune())
			newText := i.text[:i.cursorPos] + ch + i.text[i.cursorPos:]
			if i.accept != nil {
				if !i.accept(newText, event.Rune()) {
					break
				}
			}
			i.text = newText
			i.cursorPos += len(ch)

I suspect the : (colon) key has a modifier in windows.

Thanks for letting me know. I couldn't replicate this on my Mac but I made a change that will hopefully fix this for you. If it still doesn't work, let me know.

That didn't seem to fix it. What fixed it for me after your latest change was adding the following here.

			} else {
				if !add(event.Rune()) {
					break
				}
			}

It looks like the problem is not the Alt key but some other modifier. So I opted for a slightly different solution. Let me know if it works for you now.
