Normally with IME/hiragana input I can type はな and transform it immediately to 花
But when I have written a whole sentence like わたしははなをかいます。and accepted this in IME I don’t know how to go back and tell the IME to suggest replacements for はな.
The same question arises with flick input on my tablet or phone. I am using the Samsung keyboard where I have fat arrows to modify the kana to be replaced, but I can only modify the sequence of kana that have not yet been treated by IME - see the picture: I can select か, かい, かいま or かいます but nothing else - I cannot go back to はな.
I’m not sure if I have made myself clear.
