So the entire command would be: ctrl-r = sqrt(3.14159265) Then type the expression to be evaluated and press enter: So if you're typing and you need to enter the square root of PI, you could calculate it on the fly like this: ctrl-r = So to quickly paste something from the system clipboard into vim (in edit mode) you would use: CTRL-r +Īnd that would paste from the system clipboard into the current buffer/document and allow you to continue typing without leaving edit mode.Īnother useful register in edit mode is the evaluation register = which will allow you to evaluate mathematical expressions as you type. The + and * registers are associated with the system clipboard. In command-mode CTRL-r is the shortcut for redo!Īnyway - So if you're typing away in edit mode and you suddenly need to paste the text from buffer t, you'd hit: CTRL-r t The way to do this is to simply press CTRL-r and then hit the key associated with the register you want to paste from. To paste from buffer t in command mode, you would use "tp or "tP depending on whether you wanted it posted before the cursor position or after it.Īlso, you can quickly paste things from any of vims registers in edit mode, without having to switch to command mode. So to copy/yank a piece of text to buffer t, you'd select the text you wanted to cut/copy/yank in visual mode and then copy it to the t buffer by pressing "ty or "td. To copy (or yank) text to a register, you highlight it using visual mode and then hit the " key and then the key associated with the register you want to copy the text to and then either the d (delete) or the y (yank) key. You can see the content of all non-empty registers in command mode using the :reg command. There are also some special buffers: " + = * : /. I'll leave macros for another day! But I'll explain registers, because there is an edit mode shortcut that will allow you to paste text from a register using a keybind in edit-mode. You can use the registers to hold macros, or to hold snippets of text. Vims registers are a massive topic unto themselves. NOTE: That's capital D, so you'd have to press shift and DĪfter hitting that keybind - the extraneous characters at the end of the line are removed and you are put straight back into edit mode, so you can carry on with your edit. You can get rid of everything to the right of the cursor using: CTRL-o D Perhaps you've started editing in the middle of a line and you've decided that everything to the right of the cursor is no longer needed. As soon as the command has done it's thing, you're straight back in edit mode and can carry on typing. I often use CTRL-o to fire off a macro, or to perform edits without leaving edit mode.Īfter pressing CTRL-o you can perform any typical command mode command by pressing the associated keybind, or by hitting the colon : and typing any command. But the edit-mode shortcuts/keybinds can help you to keep going for a while longer, without switching to command-mode.Īnother cool thing in edit mode: CTRL-o allows you to perform a single command-mode command and immediately return to edit mode. But when you are doing some serious writing or coding, unnecessarily switching modes breaks the flow a little. 3fa - would move the cursor to the third lowercase a character in the current line.Īlso, there are a few neat keybinds for edit mode: CTRL-w delete word to the left of cursor CTRL-u delete everything to the left of cursor CTRL-h backspace/delete CTRL-j insert newline (easier than reaching for the return key) CTRL-t indent current line CTRL-d un-indent current lineĪnd I know that any experienced vim users will be screaming that the whole point in vim being modal is that you do short edits and switch back to command mode. You can use motions with the f and F commands.Į.g. FC - Would go backwards to the previous uppercase C character. Likewise: fC - Would go forwards to the next uppercase C character. Fc - would move the cursor backwards to the previous lowercase c. Hitting the keys: fc - Would move the cursor forward to the next lowercase c character. F will move the cursor backwards to a particular character on the line. f will move the cursor forward to a particular character on the line. Also on the command-mode cursor movement front there are f and F.
